给出错误的注释 RequestMapping()

Question

I am starting with Spring Boot and trying to make a Rest service. I am writing a controller where there are RequestMappings to 3 methods. Two of them are working fine while the thirl annotation is giving this error while writing the code.

Multiple markers at this line - Syntax error, insert "enum Identifier" to complete EnumHeader - Syntax error, insert "EnumBody" to complete EnumDeclaration

I tried everything from other answers but cant seem to find out the issue. Here is my code for the Controller-

package io.springboot.topics;

import java.util.Arrays;
import java.util.List;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.web.bind.annotation.PathVariable;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RestController;

@RestController
public class TopicsController {

    @Autowired
    private TopicSrvice topicService;

    @RequestMapping("/topics")
    public List<Topic> getAllTopics() {
        return topicService.getAllTopics();
    }
    @RequestMapping("/topics/{id}")
    public Topic getTopic(@PathVariable String id) {
        return topicService.getTopic(id);
    }

 @RequestMapping(method=RequestMethod.POST,value="/topics")

}

The error is coming in the last line ie last Requestmapping().

Answer 1

A bit late but for those that are just finding this issue: You need to type in the actual method under the @RequestMapping. Eclipse gives an issue when you stop at this stage but once you write your method, you are good to go. At least that is what worked for me.

So:

@RequestMapping(method=RequestMethod.POST,value="/topics")
public ... {
//your method
}

Answer 2

您正在为两种方法编写 /topics URL，一种用于 GET，一种用于 POST，Spring 不支持此配置，您可以更改两种不同方法的 url，也可以编写具有 url /topics 和 HttpMethod 数组的单个方法，例如方法 = { RequestMethod.GET, RequestMethod.POST }
