问题：

Spring Boot云配置服务器和客户端执行器endpoint不工作

南门建章
2023-03-14

我目前正在设置一些Spring boot应用程序，其中一个将是配置服务器，其他将是客户端。例如：

  1. 配置服务器
  2. 资源服务器
  3. web ui（也是一个带有Spring Security和apache互动程序的引导应用程序）

我面临的问题是，在web ui中，执行器endpoint不工作，它们给出了401个错误。

web ui中Spring Security配置的以下代码id

@Configuration
@EnableWebSecurity
@EnableGlobalMethodSecurity(prePostEnabled = true)
public class SpringSecurityConfiguration extends WebSecurityConfigurerAdapter {
    @Autowired
    private CustomAuthenticationProvider authenticationProvider;

    @Bean
    public BCryptPasswordEncoder passwordEncoder() {
        return new BCryptPasswordEncoder();
    }

    @Override
    protected void configure(AuthenticationManagerBuilder auth) throws Exception {
        auth.authenticationProvider(authenticationProvider);
    }

    @Override
    public void configure(HttpSecurity http) throws Exception {
        http
            .csrf()
            .disable();
            http
        .authorizeRequests()
            .antMatchers("/", "/login").permitAll()
            .antMatchers("/resources/**").permitAll()
            .antMatchers("**/actuator/**").permitAll()
            .anyRequest().authenticated()
            .and()
            .formLogin().loginPage("/login").failureUrl("/login?error")
            .usernameParameter("username").passwordParameter("password")
            .defaultSuccessUrl("/dashboard").loginProcessingUrl("/processLogin")
            .and()
            .logout().logoutUrl("/logoutProcessUrl").logoutSuccessUrl("/login?logout")
            .and()
            .exceptionHandling().accessDeniedPage("/login?error")
            .and().httpBasic();
        http.sessionManagement().maximumSessions(1).expiredUrl("/login?session");
    }

    @Bean
    public CustomAuthenticationSuccessHandler customAuthenticationSuccessHandler() {
        return new CustomAuthenticationSuccessHandler();
    }}

Spring配置代码

@Configuration
@EnableWebMvc
@ComponentScan("in.gov.indianrail.hrms.*")
public class SpringConfiguration extends WebMvcConfigurerAdapter {

    @Override
    public void addResourceHandlers(ResourceHandlerRegistry registry) {
        registry.addResourceHandler("/resources/**").addResourceLocations("/resources/");
    }

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

    @Bean
    public TilesConfigurer tilesConfigurer() {
        TilesConfigurer tilesConfigurer = new TilesConfigurer();
        tilesConfigurer.setDefinitions(new String[]{"/WEB-INF/views/tiles/hrms-tiles.xml"});
        tilesConfigurer.setCheckRefresh(true);
        return tilesConfigurer;
    }

    @Override
    public void configureViewResolvers(ViewResolverRegistry registry) {
        TilesViewResolver viewResolver = new TilesViewResolver();
        registry.viewResolver(viewResolver);
    }

    @Bean
    public ReloadableResourceBundleMessageSource messageSource() {
        ReloadableResourceBundleMessageSource messageSource = new ReloadableResourceBundleMessageSource();
        messageSource.setBasename("classpath:messages");
        messageSource.setDefaultEncoding("UTF-8");
        return messageSource;
    }

    @Bean
    public LocaleChangeInterceptor localeInterceptor() {
        LocaleChangeInterceptor interceptor = new LocaleChangeInterceptor();
        interceptor.setParamName("lang");
        return interceptor;
    }

    @Override
    public void addInterceptors(InterceptorRegistry registry) {
        registry.addInterceptor(localeInterceptor());
    }

    @Bean
    public CookieLocaleResolver localeResolver() {
        CookieLocaleResolver localeResolver = new CookieLocaleResolver();
        localeResolver.setDefaultLocale(Locale.ENGLISH);
        localeResolver.setCookieName("irhrms-locale-cookie");
        localeResolver.setCookieMaxAge(3600);
        return localeResolver;
    }

    @Bean
    public CommonsMultipartResolver multipartResolver() {
        CommonsMultipartResolver multipartResolver = new CommonsMultipartResolver();
        multipartResolver.setDefaultEncoding("utf-8");
        return multipartResolver;
    }

    @Bean
    public RestTemplate restTemplate() {
        return new RestTemplate();
    }
}

项目bootstrap.properties文件我添加了以下内容

spring.application.name=web-server
spring.jmx.default-domain=web-server
spring.cloud.config.uri=http://localhost:20000/config-server
#spring.cloud.config.uri=http://localhost:8080/config-server/
management.security.enable=false
management.endpoints.web.exposure.include=*
management.context-path=/actuator
endpoints.actuator.enabled=true
endpoints.logfile.enabled=true

当我点击执行器endpoint时返回的错误，比如刷新/执行器/刷新后请求，我得到了以下错误

如果我发出GET请求，它会返回

{
"timestamp": 1539057951282,
"status": 401,
"error": "Unauthorized",
"message": "Unauthorized",
"path": "/actuator/refresh"
}

那么，有谁能帮我找到错误的地方吗。

@ControllerAdvice
public class GlobalExceptionHandler {

    private static final String DEFAULT_ERROR_VIEW = "error";
    private static final Logger LOGGER = LoggerFactory.getLogger(GlobalExceptionHandler.class);

    @ExceptionHandler(value = Exception.class)
    public ModelAndView defaultErrorHandler(HttpServletRequest request, Exception e) {
        ModelAndView mav = new ModelAndView();
        mav.addObject("exception", e);
        mav.addObject("url", request.getRequestURI());
        mav.setViewName(DEFAULT_ERROR_VIEW);
        return mav;
    }
}

替换您的异常处理程序。实际上，视图解析器会找到名为error的模板。如果视图解析器找不到模板文件夹中的html，它将使用默认文件夹，其中模型中需要时间戳。

希望这可能会奏效，否则也可以尝试另一种选择，在应用程序中添加以下行。属性。

server.error.whitelabel.enabled=false
