springMVC中使用ajax来接收Controller传输的数据demo

2017-10-25 09:06 435 查看

首先说明一下，传输的数据格式是为json格式的。因为用到了json，需要在springmvc的配置文件里面配置json数据的转换器，这个很重要，并且需要引入一下三个jar包、这是传输json格式必须得jar包：

jackson-core-2.6.6.jar
jackson-databind-2.6.7.jar
jackson-annotations-2.6.0.jar
jackson-all-1.6.7.jar（非必须）

@RequestMapping(value = "ajax.do")
public @ResponseBody Map<String, Object> ajaxTest(String name, String age) {
System.out.println(name+"------"+age);
Map<String, Object> userMap = new HashMap<String, Object>();
userMap.put("name", "zhou");
userMap.put("age", "23");
userMap.put("gender", "男");
