命令行工具CURL

基于spring-boot的restful

先贴个后台代码

package com.example.rest;

import java.util.ArrayList;
import java.util.Date;
import java.util.HashMap;
import java.util.List;
import java.util.Map;

import javax.servlet.http.HttpServletRequest;

import org.springframework.web.bind.annotation.GetMapping;
import org.springframework.web.bind.annotation.PathVariable;

import org.springframework.web.bind.annotation.RequestBody;
import org.springframework.web.bind.annotation.RequestMapping;

@RestController

	private static final Log log = LogFactory.getLog(StudentController.class);

	}

	// required默认等于ture，当等于ture时，value值不传，会报400错误

用命令行测试：

POST 请求：curl -H "Content-Type:application/json" -X POST --data '{"name":"West World","creatDate":"2016-08-22","used":"true"}' http://localhost:8080/student
DELET 请求： curl -X DELECT https://localhost:8080/student/100/
PUT 请求：curl -H "Content-Type:application/json" -X PUT -data '{"name":"West World","creatDate":"2016-08-22","used":"true"}' http://localhost:8080/student/1
