- /blog/ 1 HTTP GET => 得到id = 1 的blog
- /blog/1 HTTP DELETE => 删除 id = 1 的blog
- /blog/1 HTTP PUT => 更新id = 1 的blog
- /blog HTTP POST => 新增BLOG
首先,我们带着如下三
个问题
查看本文。
1.
如何在java构造没有扩展名的RESTful url,如 /forms/1,而不是 /forms/1.do
2. 由于我们要构造没有扩展名的url本来是处理静态资源的容器映射的,现在被我们的spring占用了,冲突怎么解决?
3. 浏览器的form标签不支持提交delete,put请求,如何曲线解决?
spring mvc rest 实现
spring mvc的resturl是通过@RequestMapping 及@PathVariable
annotation提供的,通过如@RequestMapping(value="/blog/{id}",method=RequestMethod.DELETE)即可处理/blog/1
的delete请求.
- @RequestMapping (value= "/blog/{id}" ,method=RequestMethod.DELETE)
- public ModelAndView delete( @PathVariable Long id,HttpServletRequest request,HttpServletResponse response) {
- blogManager.removeById(id);
- return new ModelAndView(LIST_ACTION);
- }
@RequestMapping(value="/blog/{id}",method=RequestMethod.DELETE) public ModelAndView delete(@PathVariable Long id,HttpServletRequest request,HttpServletResponse response) { blogManager.removeById(id); return new ModelAndView(LIST_ACTION); }
@RequestMapping @PathVariable如果URL中带参数,则配合使用,如
- @RequestMapping (value= "/blog/{blogId}/message/{msgId}" ,method=RequestMethod.DELETE)
- public ModelAndView delete( @PathVariable ( "blogId" ) Long blogId, @PathVariable ( "msgId" ) Long msgId,HttpServletRequest request,HttpServletResponse response) {
- }
@RequestMapping(value="/blog/{blogId}/message/{msgId}",method=RequestMethod.DELETE) public ModelAndView delete(@PathVariable("blogId") Long blogId,@PathVariable("msgId") Long msgId,HttpServletRequest request,HttpServletResponse response) { }
spring rest配置指南
1. spring mvc web.xml配置
- <!-- 该servlet为tomcat,jetty等容器提供,将静态资源映射从/改为/static/目录,如原来访问 http://localhost/foo.css ,现在http://localhost/static/foo.css -->
- < servlet-mapping >
- < servlet-name > default </ servlet-name >
- < url-pattern > /static/* </ url-pattern >
- </ servlet-mapping >
- < servlet >
- < servlet-name > springmvc </ servlet-name >
- < servlet-class > org.springframework.web.servlet.DispatcherServlet </ servlet-class >
- < load-on-startup > 1 </ load-on-startup >
- </ servlet >
- <!-- URL重写filter,用于将访问静态资源http://localhost/foo.css 转为http://localhost/static/foo.css -->
- < filter >
- < filter-name > UrlRewriteFilter </ filter-name >
- < filter-class > org.tuckey.web.filters.urlrewrite.UrlRewriteFilter </ filter-class >
- < init-param >
- < param-name > confReloadCheckInterval </ param-name >
- < param-value > 60 </ param-value >
- </ init-param >
- < init-param >
- < param-name > logLevel </ param-name >
- < param-value > DEBUG </ param-value >
- </ init-param >
- </ filter >
- < filter-mapping >
- < filter-name > UrlRewriteFilter </ filter-name >
- < url-pattern > /* </ url-pattern >
- </ filter-mapping >
- <!-- 覆盖default servlet的/, springmvc servlet将处理原来处理静态资源的映射 -->
- < servlet-mapping >
- < servlet-name > springmvc </ servlet-name >
- < url-pattern > / </ url-pattern >
- </ servlet-mapping >
- <!-- 浏览器不支持put,delete等method,由该filter将/blog?_method=delete转换为标准的http delete方法 -->
- < filter >
- < filter-name > HiddenHttpMethodFilter </ filter-name >
- < filter-class > org.springframework.web.filter.HiddenHttpMethodFilter </ filter-class >
- </ filter >
- < filter-mapping >
- < filter-name > HiddenHttpMethodFilter </ filter-name >
- < servlet-name > springmvc </ servlet-name >
- </ filter-mapping >
<!-- 该servlet为tomcat,jetty等容器提供,将静态资源映射从/改为/static/目录,如原来访问 http://localhost/foo.css ,现在http://localhost/static/foo.css --> <servlet-mapping> <servlet-name>default</servlet-name> <url-pattern>/static/*</url-pattern> </servlet-mapping> <servlet> <servlet-name>springmvc</servlet-name> <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class> <load-on-startup>1</load-on-startup> </servlet> <!-- URL重写filter,用于将访问静态资源http://localhost/foo.css 转为http://localhost/static/foo.css --> <filter> <filter-name>UrlRewriteFilter</filter-name> <filter-class>org.tuckey.web.filters.urlrewrite.UrlRewriteFilter</filter-class> <init-param> <param-name>confReloadCheckInterval</param-name> <param-value>60</param-value> </init-param> <init-param> <param-name>logLevel</param-name> <param-value>DEBUG</param-value> </init-param> </filter> <filter-mapping> <filter-name>UrlRewriteFilter</filter-name> <url-pattern>/*</url-pattern> </filter-mapping> <!-- 覆盖default servlet的/, springmvc servlet将处理原来处理静态资源的映射 --> <servlet-mapping> <servlet-name>springmvc</servlet-name> <url-pattern>/</url-pattern> </servlet-mapping> <!-- 浏览器不支持put,delete等method,由该filter将/blog?_method=delete转换为标准的http delete方法 --> <filter> <filter-name>HiddenHttpMethodFilter</filter-name> <filter-class>org.springframework.web.filter.HiddenHttpMethodFilter</filter-class> </filter> <filter-mapping> <filter-name>HiddenHttpMethodFilter</filter-name> <servlet-name>springmvc</servlet-name> </filter-mapping>
2. webapp/WEB-INF/springmvc-servlet.xml配置,使用如下两个class激活@RequestMapping annotation
- <bean class = "org.springframework.web.servlet.mvc.annotation.DefaultAnnotationHandlerMapping" />
- <bean class = "org.springframework.web.servlet.mvc.annotation.AnnotationMethodHandlerAdapter" />
<bean class="org.springframework.web.servlet.mvc.annotation.DefaultAnnotationHandlerMapping"/> <bean class="org.springframework.web.servlet.mvc.annotation.AnnotationMethodHandlerAdapter"/>
完整配置
- <beans default -autowire= "byName" >
- <!-- 自动搜索@Controller 标注的类 -->
- <context:component-scan base-package = "com.**.controller" />
- <bean class = "org.springframework.web.servlet.mvc.annotation.DefaultAnnotationHandlerMapping" />
- <bean class = "org.springframework.web.servlet.mvc.annotation.AnnotationMethodHandlerAdapter" />
- <!-- Default ViewResolver -->
- <bean id="viewResolver" class = "org.springframework.web.servlet.view.InternalResourceViewResolver" >
- <property name="viewClass" value= "org.springframework.web.servlet.view.JstlView" />
- <property name="prefix" value= "/pages" />
- <property name="suffix" value= ".jsp" ></property>
- </bean>
- <bean id="messageSource" class = "org.springframework.context.support.ResourceBundleMessageSource" p:basename= "i18n/messages" />
- <!-- Mapping exception to the handler view -->
- <bean id="exceptionResolver" class = "org.springframework.web.servlet.handler.SimpleMappingExceptionResolver" >
- <!-- to /commons/error.jsp -->
- <property name="defaultErrorView" value= "/commons/error" />
- <property name="exceptionMappings" >
- <props>
- </props>
- </property>
- </bean>
- </beans>
<beans default-autowire="byName" > <!-- 自动搜索@Controller标注的类 --> <context:component-scan base-package="com.**.controller"/> <bean class="org.springframework.web.servlet.mvc.annotation.DefaultAnnotationHandlerMapping"/> <bean class="org.springframework.web.servlet.mvc.annotation.AnnotationMethodHandlerAdapter"/> <!-- Default ViewResolver --> <bean id="viewResolver" class="org.springframework.web.servlet.view.InternalResourceViewResolver"> <property name="viewClass" value="org.springframework.web.servlet.view.JstlView"/> <property name="prefix" value="/pages"/> <property name="suffix" value=".jsp"></property> </bean> <bean id="messageSource" class="org.springframework.context.support.ResourceBundleMessageSource" p:basename="i18n/messages"/> <!-- Mapping exception to the handler view --> <bean id="exceptionResolver" class="org.springframework.web.servlet.handler.SimpleMappingExceptionResolver"> <!-- to /commons/error.jsp --> <property name="defaultErrorView" value="/commons/error"/> <property name="exceptionMappings"> <props> </props> </property> </bean> </beans>
3. Controller编写
- /**
- * @RequestMapping("/userinfo") 具有层次关系,方法级的将在类一级@RequestMapping之一,
- * 如下面示例, 访问方法级别的@RequestMapping("/new"),则URL为 /userinfo/new
- */
- @Controller
- @RequestMapping ( "/userinfo" )
- public class UserInfoController extends BaseSpringController{
- //默认多列排序,example: username desc,createTime asc
- protected static final String DEFAULT_SORT_COLUMNS = null ;
- private UserInfoManager userInfoManager;
- private final String LIST_ACTION = "redirect:/userinfo" ;
- /**
- * 通过spring自动注入
- **/
- public void setUserInfoManager(UserInfoManager manager) {
- this .userInfoManager = manager;
- }
- /** 列表 */
- @RequestMapping
- public ModelAndView index(HttpServletRequest request,HttpServletResponse response,UserInfo userInfo) {
- PageRequest<Map> pageRequest = newPageRequest(request,DEFAULT_SORT_COLUMNS);
- //pageRequest.getFilters(); //add custom filters
- Page page = this .userInfoManager.findByPageRequest(pageRequest);
- savePage(page,pageRequest,request);
- return new ModelAndView( "/userinfo/list" , "userInfo" ,userInfo);
- }
- /** 进入新增 */
- @RequestMapping (value= "/new" )
- public ModelAndView _new(HttpServletRequest request,HttpServletResponse response,UserInfo userInfo) throws Exception {
- return new ModelAndView( "/userinfo/new" , "userInfo" ,userInfo);
- }
- /** 显示 */
- @RequestMapping (value= "/{id}" )
- public ModelAndView show( @PathVariable Long id,HttpServletRequest request,HttpServletResponse response) throws Exception {
- UserInfo userInfo = (UserInfo)userInfoManager.getById(id);
- return new ModelAndView( "/userinfo/show" , "userInfo" ,userInfo);
- }
- /** 编辑 */
- @RequestMapping (value= "/{id}/edit" )
- public ModelAndView edit( @PathVariable Long id,HttpServletRequest request,HttpServletResponse response) throws Exception {
- UserInfo userInfo = (UserInfo)userInfoManager.getById(id);
- return new ModelAndView( "/userinfo/edit" , "userInfo" ,userInfo);
- }
- /** 保存新增 */
- @RequestMapping (method=RequestMethod.POST)
- public ModelAndView create(HttpServletRequest request,HttpServletResponse response,UserInfo userInfo) throws Exception {
- userInfoManager.save(userInfo);
- return new ModelAndView(LIST_ACTION);
- }
- /** 保存更新 */
- @RequestMapping (value= "/{id}" ,method=RequestMethod.PUT)
- public ModelAndView update( @PathVariable Long id,HttpServletRequest request,HttpServletResponse response) throws Exception {
- UserInfo userInfo = (UserInfo)userInfoManager.getById(id);
- bind(request,userInfo);
- userInfoManager.update(userInfo);
- return new ModelAndView(LIST_ACTION);
- }
- /** 删除 */
- @RequestMapping (value= "/{id}" ,method=RequestMethod.DELETE)
- public ModelAndView delete( @PathVariable Long id,HttpServletRequest request,HttpServletResponse response) {
- userInfoManager.removeById(id);
- return new ModelAndView(LIST_ACTION);
- }
- /** 批量删除 */
- @RequestMapping (method=RequestMethod.DELETE)
- public ModelAndView batchDelete( @RequestParam ( "items" ) Long[] items,HttpServletRequest request,HttpServletResponse response) {
- for ( int i = 0 ; i < items.length; i++) {
- userInfoManager.removeById(items[i]);
- }
- return new ModelAndView(LIST_ACTION);
- }
- }
/** * @RequestMapping("/userinfo") 具有层次关系,方法级的将在类一级@RequestMapping之一, * 如下面示例, 访问方法级别的@RequestMapping("/new"),则URL为 /userinfo/new */ @Controller @RequestMapping("/userinfo") public class UserInfoController extends BaseSpringController{ //默认多列排序,example: username desc,createTime asc protected static final String DEFAULT_SORT_COLUMNS = null; private UserInfoManager userInfoManager; private final String LIST_ACTION = "redirect:/userinfo"; /** * 通过spring自动注入 **/ public void setUserInfoManager(UserInfoManager manager) { this.userInfoManager = manager; } /** 列表 */ @RequestMapping public ModelAndView index(HttpServletRequest request,HttpServletResponse response,UserInfo userInfo) { PageRequest<Map> pageRequest = newPageRequest(request,DEFAULT_SORT_COLUMNS); //pageRequest.getFilters(); //add custom filters Page page = this.userInfoManager.findByPageRequest(pageRequest); savePage(page,pageRequest,request); return new ModelAndView("/userinfo/list","userInfo",userInfo); } /** 进入新增 */ @RequestMapping(value="/new") public ModelAndView _new(HttpServletRequest request,HttpServletResponse response,UserInfo userInfo) throws Exception { return new ModelAndView("/userinfo/new","userInfo",userInfo); } /** 显示 */ @RequestMapping(value="/{id}") public ModelAndView show(@PathVariable Long id,HttpServletRequest request,HttpServletResponse response) throws Exception { UserInfo userInfo = (UserInfo)userInfoManager.getById(id); return new ModelAndView("/userinfo/show","userInfo",userInfo); } /** 编辑 */ @RequestMapping(value="/{id}/edit") public ModelAndView edit(@PathVariable Long id,HttpServletRequest request,HttpServletResponse response) throws Exception { UserInfo userInfo = (UserInfo)userInfoManager.getById(id); return new ModelAndView("/userinfo/edit","userInfo",userInfo); } /** 保存新增 */ @RequestMapping(method=RequestMethod.POST) public ModelAndView create(HttpServletRequest request,HttpServletResponse response,UserInfo userInfo) throws Exception { userInfoManager.save(userInfo); return new ModelAndView(LIST_ACTION); } /** 保存更新 */ @RequestMapping(value="/{id}",method=RequestMethod.PUT) public ModelAndView update(@PathVariable Long id,HttpServletRequest request,HttpServletResponse response) throws Exception { UserInfo userInfo = (UserInfo)userInfoManager.getById(id); bind(request,userInfo); userInfoManager.update(userInfo); return new ModelAndView(LIST_ACTION); } /** 删除 */ @RequestMapping(value="/{id}",method=RequestMethod.DELETE) public ModelAndView delete(@PathVariable Long id,HttpServletRequest request,HttpServletResponse response) { userInfoManager.removeById(id); return new ModelAndView(LIST_ACTION); } /** 批量删除 */ @RequestMapping(method=RequestMethod.DELETE) public ModelAndView batchDelete(@RequestParam("items") Long[] items,HttpServletRequest request,HttpServletResponse response) { for(int i = 0; i < items.length; i++) { userInfoManager.removeById(items[i]); } return new ModelAndView(LIST_ACTION); } }
上面是rapid-framework新版本生成器生成的代码,以后也将应用此规则,rest url中增删改查等基本方法与Controller的方法映射规则
- /userinfo => index()
- /userinfo/new => _new()
- /userinfo/{id} => show()
- /userinfo/{id}/edit => edit()
- /userinfo POST => create()
- /userinfo/{id} PUT => update()
- /userinfo/{id} DELETE => delete()
- /userinfo DELETE => batchDelete()
/userinfo => index() /userinfo/new => _new() /userinfo/{id} => show() /userinfo/{id}/edit => edit() /userinfo POST => create() /userinfo/{id} PUT => update() /userinfo/{id} DELETE => delete() /userinfo DELETE => batchDelete()
注(不使用 /userinfo/add => add() 方法是由于add这个方法会被maxthon浏览器当做广告链接过滤掉,因为包含ad字符)
4. jsp 编写
- < form:form action = "${ctx}/userinfo/${userInfo.userId}" method = "put" >
- </ form:form >
<form:form action="${ctx}/userinfo/${userInfo.userId}" method="put"> </form:form>
生成的html内容如下, 生成一个hidden的_method=put,并于web.xml中的HiddenHttpMethodFilter配合使用,在服务端将post请求改为put请求
- <form id= "userInfo" action= "/springmvc_rest_demo/userinfo/2" method= "post" >
- <input type="hidden" name= "_method" value= "put" />
- </form>
<form id="userInfo" action="/springmvc_rest_demo/userinfo/2" method="post"> <input type="hidden" name="_method" value="put"/> </form>
另外一种方法是你可以使用ajax发送put,delete请求.
5. 静态资源的URL重写
如上我们描述,现因为将default servlet映射至/static/的子目录,现我们访问静态资源将会带一个/static/前缀.
如 /foo.gif, 现在访问该文件将是 /static/foo.gif.
那如何避免这个前缀呢,那就是应用URL
rewrite,现我们使用 http://tuckey.org/urlrewrite/
,
重写规则如下
- < urlrewrite >
- <!-- 访问jsp及jspx将不rewrite url,其它.js,.css,.gif等将重写,如 /foo.gif => /static/foo.gif -->
- < rule >
- < condition operator = "notequal" next = "and" type = "request-uri" > .*.jsp </ condition >
- < condition operator = "notequal" next = "and" type = "request-uri" > .*.jspx </ condition >
- < from > ^(/.*\..*)$ </ from >
- < to > /static$1 </ to >
- </ rule >
- </ urlrewrite >
