SpringMVC模式各种配置以及各种控制器

Web.xml

<listener>
  <listener-class>
    org.springframework.web.context.ContextLoaderListener
  </listener-class>
</listener>
<context-param>
  <param-name>contextConfigLocation</param-name>
  <param-value>classpath*:applicationContext*.xml</param-value>
</context-param>
<servlet>
  <servlet-name>spring-mvc</servlet-name>
  <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class>
  <load-on-startup>1</load-on-startup>
</servlet>
<!-- 默认路径为/WEB-INFO/[servlet]-servlet.xml ,如这为/WEB-INFO/spring-mvc-servlet.xml -->
<servlet-mapping>
  <servlet-name>spring-mvc</servlet-name>
  <url-pattern>*.do</url-pattern>
</servlet-mapping>

spring-mvc-serlvet.xml

<bean id="simpleUrlHandlerMapping" class="org.springframework.web.servlet.handler.SimpleUrlHandlerMapping">
  <property name="mappings">
    <props>
      <prop key="login.do">loginController</prop>
      <prop key="login1.do">loginController1</prop>
      <prop key="test1.do">empController</prop>
      <prop key="test.do">startController</prop>
    </props>
  </property>
</bean>
<!-- 根据返回值拼装前缀和后缀,返回页面 -->
<bean class="org.springframework.web.servlet.view.UrlBasedViewResolver">
  <property name="viewClass" value="org.springframework.web.servlet.view.JstlView"></property>
  <property name="prefix" value="/"></property>
  <property name="suffix" value=".jsp"></property>
</bean>
<!-- 跳转到控制类 -->
<bean id="startController" class="test.StartController"></bean>
<!-- 直接页面跳转,不通过控制类,通过UrlBasedViewResolver的前缀和后缀进行页面拼装并且直接返回页面 -->
<bean id="loginController" class="org.springframework.web.servlet.mvc.ParameterizableViewController">
  <property name="viewName" value="login"></property>
</bean>
<!-- 直接页面跳转另外一种方式,直接根据跳转的url进行跳转,如login1.do,则返回login,根据拼装返回/login1.jsp -->
<bean id="loginController1" class="org.springframework.web.servlet.mvc.UrlFilenameViewController"/>
<!-- 得到javaBean的实体对象控制器 -->
<bean id="empController" class="test.EmpController">
  <property name="commandClass" value="test.Emp"></property>
</bean>

applicationContext.xml
PS:对于web无配置
java类
Emp.java(实体类)

public class Emp {
  private String name;
  private String age;
  //…getter和setter
}

EmpController.java(控制类)

public class EmpController extends AbstractCommandController {
  protected ModelAndView handle(HttpServletRequest request,
    HttpServletResponse response, Object command, BindException errors) throws Exception {
    Emp emp = (Emp)command;
    System.out.println(emp.getName()+"  "+emp.getAge()+"  phone:"+request.getParameter("phone"));
    return null;
  }
}

StartController.java(控制类)

public class StartController implements Controller {
  public ModelAndView handleRequest(HttpServletRequest request,
    HttpServletResponse response) throws Exception {
    System.out.println("StartController开始启动");
    return new ModelAndView("index");
  }
}

页面编写

<a href="simple?name=text&age=28"> simple</a><button onclick="simple()">simple</button><br/>
<a href="simple1?name=text&age=28"> simple1</a><button onclick="simple1()">simple1</button><br/>
<script type="text/javascript">
function simple(){
  $.getJSON("test.do",{"name":"nameJsonTest","age":"100"},
    function(){});
}  
function simple1(){  
  $.getJSON("test1.do",
    {"name":"nameJsonTest","age":"100","phone":"120"},
    function(){});
}
