Question

我使用注释配置了Spring Boot 我有以下文件
1）用于配置弹簧启动的AppStarter类

 
        @Configuration
        @EnableAutoConfiguration
        @PropertySource(value = "classpath:app.properties", ignoreResourceNotFound = true)
        @ComponentScan(basePackages = "com.sample.config")
        public class AppStarter extends SpringBootServletInitializer{

        @Value("${server.contextPath}")
        private String contextPath;

        @Value("${server.port:8080}")
        private String port;

        @Bean
        public static PropertySourcesPlaceholderConfigurer propertyPlaceholderConfigurer() {
            return new PropertySourcesPlaceholderConfigurer();
        }

        @Bean
        public EmbeddedServletContainerFactory servletContainer() {
            TomcatEmbeddedServletContainerFactory factory = new TomcatEmbeddedServletContainerFactory();
            factory.setPort(Integer.valueOf(port));
            factory.setContextPath(contextPath);
            factory.addErrorPages(new ErrorPage(HttpStatus.NOT_FOUND, "/notfound.html"));
            return factory;
        }

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

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


        @Value("${server.contextPath}")
        private String contextPath;

        @Value("${server.port:8080}")
        private String port;

        @Bean
        public static PropertySourcesPlaceholderConfigurer propertyPlaceholderConfigurer() {
            return new PropertySourcesPlaceholderConfigurer();
        }

        @Bean
        public EmbeddedServletContainerFactory servletContainer() {
            TomcatEmbeddedServletContainerFactory factory = new TomcatEmbeddedServletContainerFactory();
            factory.setPort(Integer.valueOf(port));
            factory.setContextPath(contextPath);
            factory.addErrorPages(new ErrorPage(HttpStatus.NOT_FOUND, "/notfound.html"));
            return factory;
        }

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

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

2）WebConfig类

3）app.properties



        @Configuration
        @ComponentScan(basePackages = {"com.sample.rest"})
        @EnableWebMvc
        public class WebConfig extends WebMvcConfigurerAdapter
        {
            @Bean
            public static PropertySourcesPlaceholderConfigurer properties()
            {
                PropertySourcesPlaceholderConfigurer configurer = new PropertySourcesPlaceholderConfigurer();
                Resource[] resources = new ClassPathResource[]{new ClassPathResource("app.properties")};
                configurer.setLocations(resources);
                configurer.setIgnoreUnresolvablePlaceholders(true);
                return configurer;
            }


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

4）UserController类

core_pool_size = 100
max_pool_size = 600
queue_capacity = 160
server.port=8080
spring.view.prefix: /WEB-INF/pages/
spring.view.suffix: .jsp

5）的pom.xml

@Controller
public class UserController extends AbstractController {

    @RequestMapping(value = "/user/add")
    public String user()
    {
       return "adduser";
    }
}

6）webdu / WEB_INF / pages文件夹中的adduser.jsp

当我尝试通过localhost访问我的jsp时：8080 / sample / user / add我得到：

org.springframework.web.servlet.PageNotFound |在DispatcherServlet中找不到带有URI [/sample/WEB-INF/pages/adduser.jsp]的HTTP请求的映射，其名称为＆＃39; dispatcherServlet＆＃39;

任何人都可以就此问题提供任何帮助吗？

Answer 1

您已配置：spring.view.prefix: /WEB-INF/jsp/
但您的文件夹是：webapp/WEB_INF/pages

/jsp vs，/pages

您需要更改其中一个，以便它们匹配！

第二：你需要请求url（这是在你的控制器上写的，而不是jsp的路径！

所以使用： localhost:8080/<yourAppName>/user/add代替/sample/WEB-INF/pages/adduser.jsp

Answer 2

使用localhost：8080 / samples / user / add，您需要将控制器代码更改为此，

@Controller
@RequestMapping("/samples")
public class UserController extends AbstractController {

    @RequestMapping(value = "/user/add")
    public String user()
    {
       return "adduser";
    }
}

Answer 3

您似乎已配置了嵌入式Tomcat容器。嵌入Tomcat时不支持JSP页面。 http://docs.spring.io/spring-boot/docs/1.2.1.RELEASE/reference/htmlsingle/#boot-features-jsp-limitations

Answer 4

试试这个：

  @Override
  public void configureDefaultServletHandling(DefaultServletHandlerConfigurer   configurer) {
      configurer.enable();
  }

Spring启动无法识别JSP
