Question

当我通过浏览器访问我的应用程序时，我得到一个404（Whitelabel错误页面）。搜索后，我认为这可能是我的sitemesh过滤器的问题。

@Bean
public FilterRegistrationBean sitemesh() throws Exception {
    FilterRegistrationBean filterRegistrationBean = new FilterRegistrationBean();
    filterRegistrationBean.setFilter(new MySiteMeshFilter());
    return filterRegistrationBean;
}

MySitemeshFilter：

protected static class MySiteMeshFilter extends ConfigurableSiteMeshFilter {    
    protected void applyCustomConfiguration(SiteMeshFilterBuilder builder) {
        builder.addDecoratorPath("/*", "/decorators/basic-theme.jsp");
    }       
}

你怎么看？谢谢！

编辑：我的安全配置也是问题所在：

@Configuration
@Order(SecurityProperties.ACCESS_OVERRIDE_ORDER)
public class ApplicationSecurity extends WebSecurityConfigurerAdapter {

    @Autowired
    private MongoTemplate mongoTemplate;

    @Override
    protected void configure(HttpSecurity http) throws Exception {
        http.authorizeRequests().antMatchers("/", "/error").permitAll()
                                .antMatchers("/register*", "/login", "/lostPassword").anonymous()
                                .antMatchers("/admin","/admin**").hasRole("ADMIN")
                                .antMatchers("/user", "/user/**", "/offer/*", "/page", "/page/**").hasAnyRole("USER", "COMPANY_USER", "COMPANY_MASTER", "ADMIN")
                                .antMatchers("/company", "/company/**").hasAnyRole("COMPANY_USER", "COMPANY_MASTER", "ADMIN")
                                .anyRequest().authenticated()
                                .and()
                                .formLogin().loginPage("/login").failureUrl("/login?error=true").usernameParameter("username").passwordParameter("password").loginProcessingUrl("/security_check")
                                .successHandler(new MyAuthenticationSuccessHandler(this.mongoTemplate));

        http.logout().logoutUrl("/logout").invalidateHttpSession(true).logoutSuccessUrl("/");
    }

    @Override
    public void configure(AuthenticationManagerBuilder auth) throws Exception {
        auth.userDetailsService(new MyUserDetailsService(this.mongoTemplate)).passwordEncoder(new ShaPasswordEncoder(256));
    }

}

编辑2：控制器未解析。设置@ComponentScan“basePackages”属性会有所帮助。控制器方法现在正在执行。但看起来spring boot无法找到我的视图（目录）来呈现页面。

编辑3：这是我的日志记录输出的一部分。有什么不寻常的吗？它从INFO log（log4j）“起始页”开始，我把它放在我的控制器的方法（“/”）中。触发属于RequestMapping的控制器方法，但我认为spring boot无法找到jsp。

在我的application.properties中，我添加了：

spring.view.prefix=/WEB-INF/views/
spring.view.suffix=.jsp

Answer 1

对于那些在这里找到答案的人来说，找到了＆＃39; oswservlet.view.BeanNameViewResolver的答案：没有为视图名称找到匹配的bean＆＃39; home＆＃39; ＆＃ 39;，Spring已尝试并未能找到“家庭”的视图解析器。

如果您想要投放纯HTML，则只需返回＆＃39; /home.html'来自你的控制器。 Spring将在/ src / main / resources / static下查找此文件，并相应地返回响应。
