1.上程式碼

	@ResponseBody
	@RequestMapping(value = "/json", produces={"application/json; charset=UTF-8"}, method = { RequestMethod.GET,
			RequestMethod.POST })
	public String json(HttpServletRequest request, HttpServletResponse response)
			throws Exception {
		Map<String,String> map = new HashMap<String,String>();
		map.put("name", "小花");
		map.put("age", "17");
		JSONObject obj = new JSONObject(map);
		return obj.toString();
	}
 

或者

	@RequestMapping("/json2")  
	public void json2(HttpServletRequest request,HttpServletResponse response) throws IOException{  
	    response.setContentType("application/json;charset=utf-8");  
	    PrintWriter out = response.getWriter();
	    Map<String,String> map = new HashMap<String,String>();
		map.put("name", "小紅");
	    map.put("age", "17");
		JSONObject obj = new JSONObject(map); 
	    out.write(obj.toString());  
	} 
 

2.springmvc配置檔案

      <mvc:annotation-driven/>
      
      <!-- 通過mvc:resources設定靜態資源，這樣servlet就會處理這些靜態資源，而不通過控制器 -->
      <!-- 設定不過濾內容，比如:css,jquery,img 等資原始檔 -->
      <mvc:resources location="/*.html" mapping="/**.html" />
      <mvc:resources location="/css/*" mapping="/css/**" />
      <mvc:resources location="/js/*" mapping="/js/**" />
      <mvc:resources location="/images/*" mapping="/images/**" />
      <!--

      		<property name="prefix" value="/WEB-INF/jsp/"/>
      		<property name="suffix" value=".jsp"/>
      </bean>
      -->
</beans>
