我在构建可执行的 spring boot jar 文件时遇到问题。
配置:
@SpringBootApplication
public class RootConfig {
public static void main(String[] args) {
SpringApplication.run(RootConfig.class, args);
}
@Bean
public ViewResolver viewResolver() {
InternalResourceViewResolver resolver = new InternalResourceViewResolver();
resolver.setPrefix("/WEB-INF/views/");
resolver.setSuffix(".jsp");
resolver.setExposeContextBeansAsAttributes(true);
return resolver;
}
}
Controller :
@Controller
public class Index {
@RequestMapping(value = "/")
public String index() {
return "index";
}
}

从想法开始:
从命令行启动可执行jar:
如何解决这样的问题？
最佳答案
运行使用嵌入式 servlet 容器(并打包为可执行存档)的 Spring Boot 应用程序时，JSP 支持存在一些限制。
- With Tomcat it should work if you use war packaging, i.e. an executable war will work, and will also be deployable to a standard container (not limited to, but including Tomcat). An executable jar will not work because of a hard coded file pattern in Tomcat.
- With Jetty it should work if you use war packaging, i.e. an executable war will work, and will also be deployable to any standard container.
