Question

请帮忙。我正在开发一个使用Spring JPA，Hateoas和Spring Data Rest MVC的Spring Boot应用程序。该应用程序可以分为RESTFul API和Web App两个主要部分。 Restful API完美运行。现在唯一的问题是让我的JSP页面工作。尝试http://localhost:9003/home时，我收到以下日志消息。

2015-04-06 21:09:02.016 WARN 6702 --- [nio-9003-exec-3] o.s.web.servlet.PageNotFound : No mapping found for HTTP request with URI [/WEB-INF/jsp/index.jsp] in DispatcherServlet with name 'dispatcherServletRegistration'

Application.java

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.boot.context.web.SpringBootServletInitializer;
import org.springframework.context.annotation.Bean;
import org.springframework.data.jpa.repository.config.EnableJpaRepositories;
import org.springframework.web.servlet.ViewResolver;
import org.springframework.web.servlet.config.annotation.EnableWebMvc;
import org.springframework.web.servlet.view.InternalResourceViewResolver;

@SpringBootApplication
@EnableJpaRepositories
@EnableWebMvc

public class Application {

    public static void main(String[] args) {
        SpringApplication.run(Application.class, args);
    }

    @Bean
    public ViewResolver viewResolver() {
       InternalResourceViewResolver viewResolver = new InternalResourceViewResolver();
       viewResolver.setPrefix("/WEB-INF/jsp/");
       viewResolver.setSuffix(".jsp");
       return viewResolver;
   }

}

WebController.java

import org.springframework.stereotype.Controller;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;
import org.springframework.web.servlet.ModelAndView;

@Controller
public class WebController {

    @RequestMapping(value = "/home", method=RequestMethod.GET)
    @ResponseStatus(HttpStatus.OK)
    public ModelAndView index() {
        return new ModelAndView("index");
    }

}

DVDController.java

import com.stalinkay.rentadvd.domain.DVD;
import com.stalinkay.rentadvd.service.DVDService;
import java.util.List;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.hateoas.Resource;
import org.springframework.http.HttpHeaders;
import org.springframework.http.HttpStatus;
import org.springframework.http.MediaType;
import org.springframework.web.bind.annotation.PathVariable;
import org.springframework.web.bind.annotation.RequestBody;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;
import org.springframework.web.bind.annotation.ResponseStatus;
import org.springframework.web.bind.annotation.RestController;

@RestController
@RequestMapping("/dvd")
public class DVDController {

    private final DVDService dvdService;

    @Autowired
    public DVDController(DVDService dvdService) {
        this.dvdService = dvdService;
    }

    /**
     * Create DVD
     *
     * @param requestDVD Spring uses the RequestBody to create a new DVD
     * to save to the database
     * @return
     */
    @RequestMapping(value = "", method = RequestMethod.POST, consumes = MediaType.APPLICATION_JSON_VALUE, produces = MediaType.APPLICATION_JSON_VALUE)
    @ResponseStatus(HttpStatus.CREATED)
    HttpHeaders create(@RequestBody DVD requestDVD) {
        return dvdService.create(requestDVD);
    }

    /**
     * Retrieve DVD
     *
     * @param dvdid
     * @return
     */
    @RequestMapping(value = "/{dvdid}", method = RequestMethod.GET, produces = MediaType.APPLICATION_JSON_VALUE)
    @ResponseStatus(HttpStatus.OK)
    Resource<DVD> retrieve(@PathVariable Long dvdid) {
        return dvdService.retrieve(dvdid);
    }

    /**
     * Retrieve All DVDs
     *
     * @return
     */
    @RequestMapping(value = "", method = RequestMethod.GET, produces = MediaType.APPLICATION_JSON_VALUE)
    @ResponseStatus(HttpStatus.OK)
    List<Resource<DVD>> retrieveAll() {
        return dvdService.retrieveAll();
    }

    /**
     * Update DVD
     *
     * @param requestDVD Spring uses the RequestBody to create a new DVD
     * to save to the database
     * @return
     */
    @RequestMapping(value = "", method = RequestMethod.PUT, consumes = MediaType.APPLICATION_JSON_VALUE, produces = MediaType.APPLICATION_JSON_VALUE)
    @ResponseStatus(HttpStatus.OK)
    HttpHeaders update(@RequestBody DVD requestDVD) {
        return dvdService.update(requestDVD);
    }

    /**
     * Delete DVD
     *
     * @param dvdid
     * @return
     */
    @RequestMapping(value = "/{dvdid}", method = RequestMethod.DELETE, produces = MediaType.APPLICATION_JSON_VALUE)
    @ResponseStatus(HttpStatus.OK)
    void delete(@PathVariable Long dvdid) {
        dvdService.delete(dvdid);
    }
}

我包含了我的DVDController.java，只是为了表明我正在使用@RestController作为RESTful API而@Controller用于Web App。

如何让Spring为JSP页面提供服务？我不想使用xml。我想在一个项目中同时拥有RESTful API和Web App。

提前谢谢。

这就是我最终的目标。

Application.java

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.boot.builder.SpringApplicationBuilder;
import org.springframework.boot.context.web.SpringBootServletInitializer;
import org.springframework.data.jpa.repository.config.EnableJpaRepositories;

@SpringBootApplication
@EnableJpaRepositories
public class Application extends SpringBootServletInitializer {

    @Override
    protected SpringApplicationBuilder configure(SpringApplicationBuilder application) {
        return application.sources(Application.class);
    }

    public static void main(String[] args) {
        SpringApplication.run(Application.class, args);
    }

}

将application.properties更新为：

spring.view.prefix: /WEB-INF/jsp/
spring.view.suffix: .jsp

我有@EnableWebMvc，这也导致了视图解析问题。

我通过查看Spring's spring-boot-sample-web-jsp偶然发现了这一点。

在Spring Boot Application中找不到具有URI [/WEB-INF/jsp/index.jsp]的HTTP请求的映射
