Spring Security3边学边写(N)会话管理和并行控制
基于springmvc实现restful样式的api接口。
1.Restful
Restful样式的接口将功能抽象为资源resource路径映射,以HTTP GET /resource/{id} 的方式访问。主要分为以下几类接口:
{id}称为路径变量,告诉restful你要对哪个资源进行查、改、删。
接口一般返回json/xml格式数据,方便服务端程序、浏览器脚本调用接口并处理返回数据。
按照Restful样式,teacher模块设计为两个资源地址:/restMvc/teachers和/restMvc/teachers/{id}。
基础的spring配置、springmvc配置、各层对象接口实现见前几节内容。
2./teachers
新建TeachersMvcResource资源类:
类中@Controller和@RequestMapping("/restMvc/teachers")注解声明了此类是Controller类并绑定到/restMvc/teachers地址,两个方法的@RequestMapping(method = { RequestMethod.GET })和@RequestMapping(method = { RequestMethod.POST })注解分别响应GET和POST请求,Contentbody里面的参数会被自动封装成Teacher teacher。
3./teacher/{id}
新增TeacherMvcResource类:
类中将服务绑定到/restMvc/teacher/{id}地址,方法的@RequestMapping(method = { RequestMethod.GET })、@RequestMapping(method = { RequestMethod.PUT })和@RequestMapping(method = { RequestMethod.DELETE })注解分别响应GET、PUT和POST请求,@PathVariable("id") Integer id接收{id}路径变量。
4.测试
rest接口可以使用服务端程序(URL、HttpClient库)、js(jquery ajax)进行访问。这里简单实用浏览器插件来测试。
使用FireFox的HttpRquester插件访问接口:
POST

5.使用服务器程序访问rest
使用HttpClient库对rest接口进行测试,测试类TestRestMvc代码如下:
输出结果如下:
get http://localhost:8080/testRest/restMvc/teachers
{"teachers":[]}
post http://localhost:8080/testRest/restMvc/teachers
{"teacher":{"id":1,"age":1,"name":"a"},"status":"y"}
get http://localhost:8080/testRest/restMvc/teachers
{"teachers":[{"id":1,"age":1,"name":"a"}]}
get http://localhost:8080/testRest/restMvc/teacher/1
{"teacher":{"id":1,"age":1,"name":"a"}}
put http://localhost:8080/testRest/restMvc/teacher/1
{"teacher":{"id":1,"age":11,"name":"aa"},"status":"y"}
get http://localhost:8080/testRest/restMvc/teachers
{"teachers":[{"id":1,"age":11,"name":"aa"}]}
delete http://localhost:8080/testRest/restMvc/teacher/1
{"status":"y"}
get http://localhost:8080/testRest/restMvc/teachers
{"teachers":[]}
1.Restful
Restful样式的接口将功能抽象为资源resource路径映射,以HTTP GET /resource/{id} 的方式访问。主要分为以下几类接口:
地址 | 请求方法 | 说明 |
/resources | GET | 获取所有资源 |
/resources | POST | 创建新资源,content中包含资源内容 |
/resource/{id} | GET | 获取编号为id的资源 |
/resource/{id} | PUT | 更新编号为id的资源,content中包含资源内容 |
/resource/{id} | DELETE | 删除编号为id的资源 |
{id}称为路径变量,告诉restful你要对哪个资源进行查、改、删。
接口一般返回json/xml格式数据,方便服务端程序、浏览器脚本调用接口并处理返回数据。
按照Restful样式,teacher模块设计为两个资源地址:/restMvc/teachers和/restMvc/teachers/{id}。
基础的spring配置、springmvc配置、各层对象接口实现见前几节内容。
2./teachers
新建TeachersMvcResource资源类:

类中@Controller和@RequestMapping("/restMvc/teachers")注解声明了此类是Controller类并绑定到/restMvc/teachers地址,两个方法的@RequestMapping(method = { RequestMethod.GET })和@RequestMapping(method = { RequestMethod.POST })注解分别响应GET和POST请求,Contentbody里面的参数会被自动封装成Teacher teacher。
3./teacher/{id}
新增TeacherMvcResource类:
package com.sunbin.test.restMvc; import javax.servlet.http.HttpServletRequest; import javax.servlet.http.HttpServletResponse; import org.springframework.web.bind.annotation.PathVariable; import org.springframework.web.bind.annotation.RequestMapping; import org.springframework.web.bind.annotation.RequestMethod; import org.springframework.web.servlet.ModelAndView; import org.springframework.web.servlet.view.json.MappingJackson2JsonView; import org.springframework.stereotype.Controller; import org.springframework.beans.factory.annotation.Autowired; import com.sunbin.test.teacher.pojo.Teacher; import com.sunbin.test.teacher.service.TeacherService; @Controller @RequestMapping("/restMvc/teacher/{id}") public class TeacherMvcResource { @Autowired private TeacherService teacherService; @RequestMapping(method = { RequestMethod.GET }) public ModelAndView get(@PathVariable("id") Integer id, HttpServletRequest arg0, HttpServletResponse arg1) throws Exception { System.out.println("RestMvc TeacherResource.get:" + id); ModelAndView modelAndView = new ModelAndView( new MappingJackson2JsonView()); Teacher teacher = new Teacher(); teacher.setId(id); modelAndView.addObject("teacher", teacherService.get(teacher)); return modelAndView; } @RequestMapping(method = { RequestMethod.PUT }) public ModelAndView put(@PathVariable("id") Integer id, Teacher teacher, HttpServletRequest arg0, HttpServletResponse arg1) throws Exception { ModelAndView modelAndView = new ModelAndView( new MappingJackson2JsonView()); // 如果teacher中不含id属性,需要单独设置 // teacher.setId(id); System.out.println("RestMvc TeacherResource.put:" + id + ":" + teacher); teacherService.update(teacher); modelAndView.addObject("status", "y"); return modelAndView; } @RequestMapping(method = { RequestMethod.DELETE }) public ModelAndView delete(@PathVariable("id") Integer id, HttpServletRequest arg0, HttpServletResponse arg1) throws Exception { ModelAndView modelAndView = new ModelAndView( new MappingJackson2JsonView()); Teacher teacher = new Teacher(); teacher.setId(id); System.out.println("RestMvc TeacherResource.delete:" + id); teacherService.remove(teacher); modelAndView.addObject("status", "y"); return modelAndView; } }

5.使用服务器程序访问rest
使用HttpClient库对rest接口进行测试,测试类TestRestMvc代码如下:
package com.sunbin.test.restMvc; import java.io.IOException; import java.util.ArrayList; import java.util.HashMap; import java.util.Iterator; import java.util.List; import java.util.Map; import java.util.Map.Entry; import org.apache.http.HttpEntity; import org.apache.http.NameValuePair; import org.apache.http.ParseException; import org.apache.http.client.ClientProtocolException; import org.apache.http.client.entity.UrlEncodedFormEntity; import org.apache.http.client.methods.HttpDelete; import org.apache.http.client.methods.HttpGet; import org.apache.http.client.methods.HttpPost; import org.apache.http.client.methods.HttpPut; import org.apache.http.impl.client.DefaultHttpClient; import org.apache.http.message.BasicNameValuePair; import org.apache.http.util.EntityUtils; public class TestRestMvc { public static final String URL_BASE = "http://localhost:8080/testRest/restMvc/"; public static void main(String[] args) throws ParseException, ClientProtocolException, IOException { String module = "teacher"; String url = ""; DefaultHttpClient client = new DefaultHttpClient(); HttpEntity entity = null; String result = ""; Map map = null; HttpGet httpGet = null; HttpPost httpPost = null; HttpPut httpPut = null; HttpDelete httpDelete = null; url = URL_BASE + module + "s"; System.out.println("get\t " + url); httpGet = new HttpGet(url); result = EntityUtils.toString(client.execute(httpGet).getEntity()); System.out.println(result); url = URL_BASE + module + "s"; System.out.println("post\t " + url); httpPost = new HttpPost(url); map = new HashMap(); map.put("name", "a"); map.put("age", "1"); entity = new UrlEncodedFormEntity(getParam(map), "UTF-8"); httpPost.setEntity(entity); result = EntityUtils.toString(client.execute(httpPost).getEntity()); System.out.println(result); url = URL_BASE + module + "s"; System.out.println("get\t " + url); httpGet = new HttpGet(url); result = EntityUtils.toString(client.execute(httpGet).getEntity()); System.out.println(result); url = URL_BASE + module + "/1"; System.out.println("get\t " + url); httpGet = new HttpGet(url); result = EntityUtils.toString(client.execute(httpGet).getEntity()); System.out.println(result); url = URL_BASE + module + "/1"; System.out.println("put\t " + url); httpPut = new HttpPut(url); map = new HashMap(); map.put("name", "aa"); map.put("age", "11"); entity = new UrlEncodedFormEntity(getParam(map), "UTF-8"); httpPut.setEntity(entity); result = EntityUtils.toString(client.execute(httpPut).getEntity()); System.out.println(result); url = URL_BASE + module + "s"; System.out.println("get\t " + url); httpGet = new HttpGet(url); result = EntityUtils.toString(client.execute(httpGet).getEntity()); System.out.println(result); url = URL_BASE + module + "/1"; System.out.println("delete\t " + url); httpDelete = new HttpDelete(url); result = EntityUtils.toString(client.execute(httpDelete).getEntity()); System.out.println(result); url = URL_BASE + module + "s"; System.out.println("get\t " + url); httpGet = new HttpGet(url); result = EntityUtils.toString(client.execute(httpGet).getEntity()); System.out.println(result); } public static List<NameValuePair> getParam(Map parameterMap) { List<NameValuePair> param = new ArrayList<NameValuePair>(); Iterator it = parameterMap.entrySet().iterator(); while (it.hasNext()) { Entry parmEntry = (Entry) it.next(); param.add(new BasicNameValuePair((String) parmEntry.getKey(), (String) parmEntry.getValue())); } return param; } }
输出结果如下:
get http://localhost:8080/testRest/restMvc/teachers
{"teachers":[]}
post http://localhost:8080/testRest/restMvc/teachers
{"teacher":{"id":1,"age":1,"name":"a"},"status":"y"}

put http://localhost:8080/testRest/restMvc/teacher/1
{"teacher":{"id":1,"age":11,"name":"aa"},"status":"y"}
get http://localhost:8080/testRest/restMvc/teachers
{"teachers":[{"id":1,"age":11,"name":"aa"}]}
delete http://localhost:8080/testRest/restMvc/teacher/1
{"status":"y"}
