java - 发布和获取未映射到 Spring 启动 - 状态：404
问题描述
我有一个简单的应用程序来测试 Spring Boot。下面是配置，包是根据 Spring 文档设置的。应用程序启动没有错误。使用带有 Eclipse 的 Spring Boot。控制器仍然没有映射到服务器，当我发布或获取它时说：
{
"timestamp": 1547026379146,
"status": 404,
"error": "Not Found",
"message": "No message available",
"path": "/postdata"
}

解决方案
请附上来自例如开发人员工具的请求，带有您正在使用的 HTTP 动词以及该请求的准确响应。我担心@GetMapping - 为什么它在花括号中？关于后期映射，也许您应该描述映射的消耗和生成部分？例如
@PostMapping(path = "/members", consumes = "application/json", produces = "application/json")
没有这些部分，我从来没有使用过@PostMapping 注释。
更新：
在主类更改控制器中删除不必要的组件扫描后，如下所示：
@RestController
public class ControllerRest {
@Autowired
private MessagesRepository msgRepo;
RestTemplate restTemplate;
@GetMapping({ "/StatusData" })
public List<Messages> index() {
return this.msgRepo.findAll();
}
@PostMapping(path = {"/postdata"})
public ResponseEntity<Messages> createBody(@RequestBody Map<String, String> body) {
Messages msgDao = new Messages();
msgDao.setTemplate((String) body.get("template"));
msgDao.setParameters((String) body.get("parameters"));
msgDao.setHsm((String) body.get("hsm"));
msgDao.setTo((String) body.get("to"));
return new ResponseEntity<Messages>(this.msgRepo.save(this.HttpStatus.OK);
}
}
