我有一个使用 spring xml 的遗留应用程序，我正在将其迁移到 spring-boot。

应用程序启动，我得到身份验证页面，映射在 applicationContext-login.xml 中。登录成功后，它应该加载 WEB-INF/client/home.jsp，但相反，它尝试加载/WEB-INF/auth/home.jsp，我得到 404。 在启动日志中，我看到它映射了所有路径。 为什么这些重定向会发生冲突？我该怎么做才能解决这个问题？它是否因为多个包含 View 解析器的@ImportResource 而遇到问题？

从安全 http 配置中提取:

    <s:http use-expressions="true" entry-point-ref="delegatingAuthenticationEntryPoint">
        <s:form-login login-page="/auth/login"
                      login-processing-url="/auth/j_spring_security_check"
                      authentication-failure-url="/auth/login-secure?loginFailed=true"
                      default-target-url="/auth/defaultEntry"/>
        <s:logout logout-url="/auth/logout" logout-success-url="/auth/logout-success" delete-cookies="jsessionid"/>
    </s:http>

它指向的 Controller :

    @RequestMapping(value = "/defaultEntry", method = RequestMethod.GET)
    public String defaultEntry() {
        if (authentication.isAuthenticated()) {
              return "redirect:/client/home";
        } else {
            return "redirect:login";
        }
    }

应用程序在 xml 文件中配置了多个 View 解析器:

• classpath*:/springContext/applicationContext-login.xml

还有其他几个遵循相同的配置模式。

我正在加载 Application.java 中的资源

    @SpringBootApplication(exclude = {DataSourceAutoConfiguration.class, HibernateJpaAutoConfiguration.class})
    //@EnableWebMvc
    @ComponentScan({"org.myCompany"})
    @ImportResource({"classpath*:/springContext/applicationContext-controllers.xml",
            "classpath*:/springContext/applicationContext-rest.xml",
            "classpath*:/springContext/applicationContext-login.xml",
            "classpath*:/springContext/applicationContext-client.xml",
            "classpath*:/springContext/applicationContext-admin.xml",
            "classpath*:/springContext/applicationContext-logging.xml",
            "classpath*:/springContext/applicationContext-web-common.xml"
    })
    public class Application extends SpringBootServletInitializer {

        public static void main(String[] args) throws UnknownHostException {
            SpringApplication app = new SpringApplication(Application.class);
            ApplicationContext ctx = app.run(args);
            Environment env = ctx.getEnvironment();

            logger.info(String.format("\n----------------------------------------------------------\n\t" +
                            "Application '%s' is running! Access URLs:\n\t" +
                            "Local: \t\thttp://localhost:%s\n\t" +
                            "External: \thttp://%s:%s\n----------------------------------------------------------",
                    env.getProperty("spring.application.name"),
                    env.getProperty("server.port"),
                    InetAddress.getLocalHost().getHostAddress(),
                    env.getProperty("server.port")));
        }

        @Bean
        public ServletRegistrationBean restDispatcher() {
            ServletRegistrationBean registration = new ServletRegistrationBean(new DispatcherServlet(),
                    "/rest/*", "/websocket/*");
            registration.setName("rest-dispatcher");
            registration.setLoadOnStartup(2);
            Map<String, String> params = new HashMap<>();
            params.put("contextConfigLocation", "classpath*:springContext/applicationContext-rest.xml");
            registration.setInitParameters(params);
            return registration;
        }

        @Bean
        public ServletRegistrationBean authDispatcher() {
            ServletRegistrationBean registration = new ServletRegistrationBean(new DispatcherServlet(), "/auth/*");
            registration.setName("auth-dispatcher");
            registration.setLoadOnStartup(2);
            Map<String, String> params = new HashMap<>();
            params.put("contextConfigLocation", "classpath*:springContext/applicationContext-login.xml");
            registration.setInitParameters(params);
            return registration;
        }

        @Bean
        public ServletRegistrationBean clientDispatcher() {
            ServletRegistrationBean registration = new ServletRegistrationBean(new DispatcherServlet(), "/client/*");
            registration.setName("client-dispatcher");
            registration.setLoadOnStartup(2);
            Map<String, String> params = new HashMap<>();
            params.put("contextConfigLocation", "classpath*:springContext/applicationContext-client.xml");
            registration.setInitParameters(params);
            return registration;
        }

    //... other servlets registration, filters registration

    }

最佳答案

您正在从登录屏幕返回 redirect:/client/home，这将由您的 loginViewResolver 处理:

<bean id="loginViewResolver" class="org.springframework.web.servlet.view.InternalResourceViewResolver">
      <property name="viewClass" value="org.springframework.web.servlet.view.JstlView"/>
      <property name="prefix" value="/WEB-INF/auth/"/>
      <property name="suffix" value=".jsp"/>
  </bean>

clientViewResolver 不会被调用，因为在 View 解析器上没有指定顺序。您可以使用 order 属性设置顺序。，

关于xml - spring-boot 使用来自 xml 配置的多个 View 解析器无法正确重定向，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/38571041/
