本文使用SpringMVC版本:
org.springframework:spring-web:4.3.9.RELEASE
写法及说明(示例代码的类上的注解是@RestController,所以方法上不需要添加@ResponseBody):
@RequestMapping("/hello")
public String test(String name,@RequestBody List<ForListReceive> list) {
/**
* 接收List的条件
* 1、使用JSON格式数据,如[{"a":"a","b":"b"}] 放在RequestBody中传递
* 2、RequestHeader中需要有 Content-Type: application/json;charset=utf8
* 3、需要在参数前加上@RequestBody
*/ System.out.println(list.get(0).getA());
return list.size()+":"+name;
} @RequestMapping("/hi")
public String hi(@RequestParam("list") List<String> list) {
/**
* 接收List<String>
* 1、Request Parameters中list=a,b,c
* 2、必须写上@RequestParam("list")
*/
System.out.println(list.get(0));
return list.size()+"";
} @RequestMapping("/hey")
public String hey(String[] list) {
/**
* 接收数组
* 1、Request Parameters中list=a,b,c 即可成功接收
*/
System.out.println(list[0].toString());
System.out.println(list[1].toString());
return list.length+"";
}
ForListReceive.java:
public class ForListReceive {
String a;
String b; public String getA() {
return a;
} public void setA(String a) {
this.a = a;
} public String getB() {
return b;
} public void setB(String b) {
this.b = b;
}
}
