Question

spring boot web默认的DispatcherServlet如何修改自定义配置mapping 映射路径？

Answer 1

可以在application.properties加入配置，如：

server.servlet-path=/api/*

另外，也可以注入一个新的ServletRegistrationBean用于映射新的url：

//自动注入spring boot默认的上传配置
@Autowired
private MultipartConfigElement multipartConfigElement;
@Autowired
private DispatcherServlet dispatcherServlet;
@Bean
public ServletRegistrationBean apiServlet() {
    ServletRegistrationBean bean = new ServletRegistrationBean(dispatcherServlet);
    //注入上传配置到自己注册的ServletRegistrationBean
    bean.addUrlMappings("/api/*");
    bean.setMultipartConfig(multipartConfigElement);
    bean.setName("apiServlet");
    return bean;
}

Answer 2

final DispatcherServlet dispatcherServlet = new DispatcherServlet();

    final AnnotationConfigWebApplicationContext applicationContext = new AnnotationConfigWebApplicationContext();
    applicationContext.scan("com.wlbank.cms");
    // applicationContext.register(BackServletConfig.class);
    dispatcherServlet.setApplicationContext(applicationContext);
    final ServletRegistrationBean<DispatcherServlet> servletRegistrationBean = new ServletRegistrationBean<>(
            dispatcherServlet, "*.jhtml", "*.jspx", "*.jsp", "*.htm");
    servletRegistrationBean.setLoadOnStartup(0);
    servletRegistrationBean.setName("cmsDispatcherServlet");
    return servletRegistrationBean;
