【SpringBoot】Rest映射及自定义_method
【Rest映射】
HelloController.java
package com.you.boot.boot.Controller;
import com.you.boot.boot.bean.Person;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;
import org.springframework.web.bind.annotation.RestController;
@RestController
public class HelloController {
@Autowired
Person person;
@RequestMapping("/person")
public Person person()
{
return person;
}
@RequestMapping(value = "/user",method = RequestMethod.GET)
public String getUser()
{
return "GET-张三";
}
@RequestMapping(value = "/user",method = RequestMethod.POST)
public String saveUser()
{
return "POST-张三";
}
@RequestMapping(value = "/user",method = RequestMethod.PUT)
public String putUser(){
return "PUT-张三";
}
@RequestMapping(value = "/user",method = RequestMethod.DELETE)
public String deleteUser()
{
return "DELETE-张三";
}
}
index.html
在下济北公游坦之
<form action="/user" method="get"> <input value="REST-GET 提交" type="submit"> </form> <form action="/user" method="post"> <input value="REST-POST 提交" type="submit"> </form> <form action="/user" method="put"> <input value="REST-PUT 提交" type="submit"> </form> <form action="/user" method="delete"> <input value="REST-DELETE 提交" type="submit"> </form> </body> </html> 效果分析：PUT和DELETE显示的全是Get，原因是下面这两个都会默认当成Get方式
处理Put和Delete
开启hiddenmethod功能
spring:
mvc:
hiddenmethod:
filter:
enabled: true
修改上面代码如下（此处delete、put可以用大写或者小写，最终会在底层转化成大写）
<form action="/user" method="post"> <input name="_method" type="hidden" value="put"> <input value="REST-PUT 提交" type="submit"> </form> <form action="/user" method="post"> <input name="_method" type="hidden" value="delete"> <input value="REST-DELETE 提交" type="submit"> </form> 【效果】RestMapping简写
@RequestMapping(value = “/user”,method = RequestMethod.GET) === @GetMapping("/user")
红色的那一行就等于蓝色的那一行
其他同理
自定义_method
methodFilter.setMethodParam("_ytz");括号里面写自己想改的
package com.you.boot.boot.config;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.web.filter.HiddenHttpMethodFilter;
@Configuration(proxyBeanMethods = false)
public class WebConfig {
@Bean
public HiddenHttpMethodFilter hiddenHttpMethodFilter()
{
HiddenHttpMethodFilter methodFilter = new HiddenHttpMethodFilter();
methodFilter.setMethodParam("_ytz");
return methodFilter;
}
}
