SpringMVC @RequestBody接收Json对象字符串 demo
springmvc 的这个 @RequestBody 用得比较少,今天看了一下,还是很方便.
@RequestBody 接收类似 [{name: "test"}, {name: "张三"}] 这样的json字符串.
先看页面:
<!DOCTYPE html><html><head><meta charset="UTF-8"><title>Insert title here</title><script src="https://code.jquery.com/jquery-3.1.1.min.js"></script><script type="text/javascript"> function test(){ var saveDataAry=[]; var data1={"name":"test"}; var data2={"name":"张三"}; saveDataAry.push(data1); saveDataAry.push(data2); $.ajax({ type:"POST", url:"http://localhost/test/student", dataType:"json", contentType:"application/json", data:JSON.stringify(saveDataAry), success:function(data){ alert(data) } }); }</script></head><body> <input type="button" onclick="test()" value="http://www.mamicode.com/测试"></body></html>
最后看后台代码:
import java.util.List;import org.springframework.web.bind.annotation.RequestBody;import org.springframework.web.bind.annotation.RequestMapping;import org.springframework.web.bind.annotation.RequestMethod;import org.springframework.web.bind.annotation.ResponseBody;import org.springframework.web.bind.annotation.RestController;@RestController@RequestMapping("/test")public class TestController { @ResponseBody @RequestMapping(value="/student",method=RequestMethod.POST) public String student(@RequestBody List<Student> students ){ for(Student s : students){ System.out.println("学生姓名:"+s.getName()); } return "ok"; }}class Student{ private String name; public String getName() { return name; } public void setName(String name) { this.name = name; } }
小结一下,这样传参数就是json字符串化.
