Spring Boot groovy编译错误:意外的令牌@ @第45行

Question

我正在尝试将Spring Boot项目中的Java控制器转换为Groovy,并在尝试编译和运行时遇到最奇怪的错误

unexpected token: @ @ line 45, column 5
@RequestMapping(value = {"/v1/foo", "/foo"}, method = GET)
^

这让我感到困惑.注释是Java或Groovy中的注释,对吧？我错过了什么？这是我的代码的抽象

// src/main/groovy/my/package/FooController.groovy, formerly .java

/// ... proper imports

@RestController
@EnableAutoConfiguration
public class FooController {

    // ... @autowire services

    @RequestMapping(value = {"/v1/foo", "/foo"}, method = GET)
    public ResponseEntity get(@RequestHeader HttpHeaders headers) {
      // do work return ResponseEntity
    }

    @RequestMapping(value = {"/v1/foo", "/foo"}, method = PUT)
    public ResponseEntity put(@RequestHeader HttpHeaders headers, @ResponseBody @Valid final MyFoo myFoo) {
      // do work return ResponseEntity
    }
}

Answer 1

所以我只是愚蠢而错过了Java和Groovy之间的关键区别

问题是value我要去的地方@RequestMapping

在Java中,{"/v1/foo", "foo"}是一个数组文字

在Groovy中,{"/v1/foo", "foo"}是一个闭包

错误消息显然没有帮助,但为了解决这个问题,我只需要更改Groovy中的注释以按照我的意图传入数组文字,而不是关闭

@RequestMapping(value = ["/v1/foo", "/foo"], method = GET)
