SpringMVC模式注解式annotation配置控制器

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

<!-- 对Web包的所有类进行扫描,完成Bean创建和自动依赖注入 -->
<context:component-scan base-package="com"/>
<!-- 启动SpringMVC注解功能,完成请求和注解POJO的映射 -->
<bean class="org.springframework.web.servlet.mvc.annotation.AnnotationMethodHandlerAdapter"></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>

applicationContext.xml
PS:对于web无配置
实体类注入:

public class User {
	private String name;
	
	private int age;
        //get和set 省略..
}

UrlParamController控制器:

@Controller
public class UrlParamController {
//user可获取到name和age的数据
  @RequestMapping(value = "/test1.do", method = RequestMethod.GET)
  public String test(@RequestParam(value = "name", required = true) String name, @RequestParam(value = "age", required = true) Integer age,User user) {
    System.out.println("emp.name:" + name);
    System.out.println("emp.age:" + age);
return "success";
  }
}

页面jsp:

function simple1(){
  $.getJSON("test1.do",{"name":"nameJsonTest","age":"100"},
    function(){});
}
