需要匯入這三個jar包

需要在spring.xml檔案新增  

<!-- 啟動註解  -->
<mvc:annotation-driven/>

   我的springmvc-config.xml配置

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
	xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
	xmlns:context="http://www.springframework.org/schema/context"
	xmlns:mvc="http://www.springframework.org/schema/mvc"
	xsi:schemaLocation="http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc-4.3.xsd
		http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd
		http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-4.3.xsd">


<!-- 啟動註解  -->
<mvc:annotation-driven/>

 <!-- 配置自動掃描的包 -->
    <context:component-scan base-package="com.hp.action"></context:component-scan>
    
    
    <!-- 配置檢視解析器 把Controller方法返回的檢視解析為實際檢視 -->
    <bean class="org.springframework.web.servlet.view.InternalResourceViewResolver">
        <!-- 字首 -->
        <property name="prefix" value="/WEB-INF/jsp/"></property>
        <!-- 字尾 -->
        <property name="suffix" value=".jsp"></property>
    </bean>
</beans>
 

我的json方法

@RequestMapping(value="/json",method=RequestMethod.GET,produces="application/json")
@ResponseBody
public HashMap hello9(){
	HashMap s = new HashMap();
	UserBean bean = new UserBean();
	bean.setName("張三");
	bean.setPwd("123");
	s.put("aaa", bean);
	return s;
} 

由於我在專案訪問前添加了路徑

@RequestMapping(value="/text")

 所以訪問前加上了/text 效果圖
