在RestController注释中找不到HTTP 404

Question

RestController不工作在spring 2.1.5-发布与Primeface6.2。

PivotController与@SpringBootApplication在同一个包中，但我无法在启动时查看有关RestController映射url的任何信息。

错误是HTTP 404未找到。

控制器类：

 @RestController
 @EnableAutoConfiguration
 @RequestMapping(path="/item")
 public class PivotController {

     @GetMapping(path="/")
     protected @ResponseBody String getItem(){
         return "item";   
     }
}

解决了！

我忘了在pom文件中插入这个！

<dependency>
        <groupId>org.springframework.boot</groupId>
        <artifactId>spring-boot-starter-data-rest</artifactId>
        <version>2.1.5.RELEASE</version>
    </dependency>

Answer 1

请添加spring的依赖项

        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-web</artifactId>
        </dependency>
