Question

我正在尝试将Spring Boot应用程序作为一个可运行的jar执行，它在从STS内部运行时运行良好，但在通过java -jar执行时尝试访问我的JSP时得到404。

@SpringBootApplication
public class MyApplication extends WebMvcConfigurerAdapter {

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

    @Bean
    public LocaleResolver localeResolver() {
        SessionLocaleResolver slr = new SessionLocaleResolver();
        slr.setDefaultLocale(Locale.US);
        return slr;
    }

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

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

    @Bean
    //Did trying commenting this part but made no difference
    public ViewResolver jspViewResolver() {
        InternalResourceViewResolver resolver = new InternalResourceViewResolver();
        resolver.setPrefix("/WEB-INF/jsp/");
        resolver.setSuffix(".jsp");
        resolver.setViewClass(JstlView.class);
        return resolver;
    }

}

application.properties

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

我在这里看到过类似的问题，但大多数都指出sufix或前缀不在application.properties或tomcat-embed-jasper中，甚至jsps不在路径/ src / main /中resources / META-INF / resources / WEB-INF / jsp（我确实在这条路径中有我的JSP）。关于我在这里可能缺少的任何想法？

Answer 1

我遇到了这个问题，对我来说，必须将嵌入式tomcat依赖项从 compile 更改为实施，

implementation('org.apache.tomcat.embed:tomcat-embed-jasper:8.0.47')

Spring Boog + JSP 404通过命令行
