java - 使用 RestController 注释找不到 HTTP 404

Question

RestController 不适用于带有 primeface 6.2 的 spring-boot 2.1.5-RELEASE 。

PivotController 与 @SpringBootApplication 位于同一包中，但在启动过程中我无法查看有关 RestController 映射 url 的任何信息。

错误是 HTTP 404 未找到。

Controller 类:

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

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

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 web的依赖

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