Java Post和Get未映射到Spring启动-状态：404

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。 应用程序启动时没有错误。在eclipse中使用Spring引导。 控制器仍然没有映射到服务器，当我发布或获取时，它会显示：

{
    "timestamp": 1547026379146,
    "status": 404,
    "error": "Not Found",
    "message": "No message available",
    "path": "/postdata"
}

请附上您正在使用的HTTP谓词开发人员工具的请求以及该请求的确切响应。我关心@GetMapping——为什么它用大括号括起来？ 关于后期映射，也许您应该描述映射的使用和生成部分？ 例如

我从未使用过没有这些部分的@PostMapping注释

更新：

删除主类中不必要的组件扫描后，更改控制器，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);
    }
}

@RestController
公共类控制器测试{
@自动连线
私人信息回复msgRepo；
rest模板rest模板；
@GetMapping（{“/StatusData”}）
公共列表索引（）{
返回这个.msgRepo.findAll（）；
}
@PostMapping（路径={“/postdata”}）
公共响应主体createBody（@RequestBody映射主体）{
Messages msgDao=新消息（）；
msgDao.setTemplate（（字符串）body.get（“模板”）；
msgDao.setParameters（（字符串）body.get（“参数”）；
msgDao.setHsm（（String）body.get（“hsm”）；
msgDao.setTo（（String）body.get（“to”）；
返回新的ResponseEntity（this.msgRepo.save（this.HttpStatus.OK））；
}
}

将上下文路径添加到application.properties文件或application.yml（以您使用的为准）

server.servlet.contextPath=/springbootapi

点击端点：POST方法的端点将是：

：{PORT}/springbootapi/postdata

为什么不静态地提供端口呢？我认为端口应该是这样的：

server.port=8080

---

我不明白你为什么要将@RequestBody与

映射一起使用。

请尝试以下代码：

@Autowired
private MessagesRepository msgRepo;

 @PostMapping("/postdata")
public ResponseEntity<Object> createBody(@RequestBody Message message) {
    Message saveMessage= msgRepo.save(message);

URI location = ServletUriComponentsBuilder.fromCurrentRequest().path("/{id}")
        .buildAndExpand(saveMessage.getId()).toUri();

return ResponseEntity.created(location).build();
}

@Autowired
私人信息回复msgRepo；
@后映射（“/postdata”）
public ResponseEntity createBody（@RequestBody Message）{
Message saveMessage=msgRepo.save（Message）；
URI位置=ServletUriComponentsBuilder.fromCurrentRequest（）.path（“/{id}”）
.buildAndExpand（saveMessage.getId（））.toUri（）；
返回ResponseEntity.created（location.build（）；
}

添加你的应用程序。属性get

/WhatsAppStatusData

怎么样？这行得通吗？你的

应用程序中是否有类似于
server.servlet.context-path:/api的东西。yml
？你用于请求的确切url是什么？我认为这不是在你的控制器中注入多个bean的正确方法…`@Autowired private Messages msgDao；private Messages Repository msgRepo；`You need:`@Autowired private Messages msgDao；@Autowired private Messages Repository msgRepo；`在日志中进行此更改后，我看不到get和post映射。此外，邮递员会抛出404@enemyofnone您确定要发送
应用程序吗/json
request？您可以发布请求的内容吗？curl-X post\\\-H'内容类型：application/json'\-H'邮递员令牌：98b7a597-7844-4620-b149-ecb3bf339193'\-H'缓存控制：无缓存'\-d'{“消息”：[{“to:+911111234”，“hsm:{”模板：{“欢迎通知”\u演示”，“参数：{“1:“abc”，“2:“测试”}}]“@EstebanMarin还添加了application.properties我关闭了它，错误地复制了最后3行，因此不需要提供端口。默认情况下，它从8080端口启动。它也应该在默认上下文中正常启动尝试了这两个建议，还删除了server.port属性，没有起作用：（我认为你的控制器Bean没有被上下文加载。在上面添加@Autowired`private messages repository msgRepo；`不走运，问题是在日志中我没有看到任何帖子或被映射。你可以发布你的pom吗？我想如果没有运行POST或GET映射代码。还有变量restTemplate？。我从你的代码中找不到它？
