java - 如何删除 Spring Boot 应用程序中的白色标签错误页面？

Question

我正在运行一个 Spring Boot 应用程序。当我输入 URL http://localhost:8080 (或 http://localhost:8080/index.jsp)时，我希望加载 index.jsp 文件，但我在浏览器上收到以下错误。

Whitelabel Error Page

    This application has no explicit mapping for /error, so you are seeing this as a fallback.

    There was an unexpected error (type=Not Found, status=404).
    No message available

我的index.jsp存在于webContent目录中，我的AppConfig类如下

@EnableJpaRepositories("com.test.repository")
@Configuration
@EnableTransactionManagement
@ComponentScan(basePackages="com.test.domain")
@PropertySource(value={"classpath:application.properties"})
public class AppConfig {
    @Autowired
    private Environment environment;

    @Bean
    public DataSource dataSource() {
        DriverManagerDataSource datasource = new DriverManagerDataSource();
        datasource.setDriverClassName(environment.getRequiredProperty("spring.datasource.driver-class-name"));
        datasource.setUrl(environment.getRequiredProperty("spring.datasource.url"));
        datasource.setUsername(environment.getRequiredProperty("spring.datasource.username"));
        datasource.setPassword(environment.getRequiredProperty("spring.datasource.password"));
        return datasource;
    }

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

    @Bean
    public WebMvcConfigurerAdapter forwarderToIndex() {
        return new WebMvcConfigurerAdapter() {
            @Override
            public void addViewControllers(ViewControllerRegistry registry) {
                registry.addViewController("/").setViewName("forward://index.jsp");
            }
        };
    }

}

我还提到了this这对我没有帮助。如何消除此错误并重定向到index.jsp？

Answer 1

您可以使用以下方法删除错误页面自动配置

exclude = { ErrorMvcAutoConfiguration.class } 

在您的@SpringBootApplication注释中

即

 @SpringBootApplication(scanBasePackages = { "com.myapp.app" }, exclude = { ErrorMvcAutoConfiguration.class })

如果您没有使用

@SpringBootApplication 你可以通过放置在你的配置类中来做到这一点

@EnableAutoConfiguration( exclude = { ErrorMvcAutoConfiguration.class })
