我正在使用这个控制器启动一个spring boot应用程序。

@RestController @RequestMapping({"/api"}) public class ProduitImmobilierController { Logger logger = LoggerFactory.getLogger(ProduitImmobilierController.class); @Autowired private ProduitImmobilierService produitImmobilierService; @RequestMapping(value = "/produitimmobilier/all/{pageSize}/{page}", method = RequestMethod.GET, produces = {"text/plain;", MediaType.APPLICATION_JSON_VALUE}, consumes = {"text/plain;charset=UTF-8", MediaType.APPLICATION_JSON_VALUE}) public @ResponseBody List findAll(@PathVariable("pageSize") int pageSize, @PathVariable("page") int page){ logger.info("CONTROLLER PRODUITIMMOBILIERSERVICE CA PASSE"); return produitImmobilierService.findAll(pageSize, page); }

我检查应用程序是否正在监听端口8080我尝试在firefox上使用此URL访问此控制器

http://localhost:8080/api/produitimmobilier/all/5/1

我得到了这个错误

Whitelabel Error Page This application has no explicit mapping for /error, so you are seeing this as a fallback. Wed Nov 13 20:48:53 CET 2019 There was an unexpected error (type=Not Found, status=404). No message available

这是项目树

我怎么解决它呢？

我添加了pom.xml

4.0.0 org.springframework.boot spring-boot-starter-parent 2.1.9.RELEASE com.example demoImmobilierBack 0.0.1-SNAPSHOT demoImmobilierBack Demo project for Spring Boot 1.8 mysql mysql-connector-java 8.0.17 org.hibernate.hql hibernate-hql-parser 1.5.0.Final org.springframework.boot spring-boot-starter-data-jpa javax.persistence javax.persistence-api 2.2 org.springframework.boot spring-boot-starter-web org.springframework.boot spring-boot-starter-test test org.springframework.boot spring-boot-starter-thymeleaf com.h2database h2 test org.projectlombok lombok 1.18.10 provided org.springframework.boot spring-boot-maven-plugin spring-releases Spring Releases https://repo.spring.io/libs-release org.jboss.repository.releases JBoss Maven Release Repository https://repository.jboss.org/nexus/content/repositories/releases spring-releases Spring Releases https://repo.spring.io/libs-release

当我使用以下url点击应用程序时：http://localhost:8080/api/produitimmobilier/all/5/1
