spring boot 中设置默认网页的方法
废话不多说，直接上代码，相信都能看的懂
一共两布，第一步，创建Interceptor拦截
packagecom.cy.example.config;
importjavax.servlet.http.HttpServletRequest;
importjavax.servlet.http.HttpServletResponse;
importjavax.servlet.http.HttpSession;
importorg.slf4j.Logger;
importorg.slf4j.LoggerFactory;
importorg.springframework.web.servlet.HandlerInterceptor;
importorg.springframework.web.servlet.ModelAndView;
publicclassLoginInterceptorimplementsHandlerInterceptor{
privateLoggerlogger=LoggerFactory.getLogger(LoginInterceptor.class);
publicvoidpostHandle(HttpServletRequestrequest,
HttpServletResponseresponse,Objecthandler,
ModelAndViewmodelAndView)throwsException{
//TODOAuto-generatedmethodstub
}
publicvoidafterCompletion(HttpServletRequestrequest,
HttpServletResponseresponse,Objecthandler,Exceptionex)
throwsException{
//TODOAuto-generatedmethodstub
}
publicbooleanpreHandle(HttpServletRequestrequest,
HttpServletResponseresponse,Objecthandler)throwsException{
//TODOAuto-generatedmethodstub
//获取session
HttpSessionsession=request.getSession(true);
logger.info("----进入登录拦截器--url："+request.getServletPath()+"-----");
if(session.getAttribute(WebConfig.LOGIN_USER)==null){
logger.info("------跳转到login页面-----");
response.sendRedirect(request.getContextPath()+"/index");
returnfalse;
}else{
session.setAttribute(WebConfig.LOGIN_USER,session.getAttribute(WebConfig.LOGIN_USER));
returntrue;
}
}
}
第二步，注册创建的拦截器
packagecom.cy.example.config;
importorg.springframework.context.annotation.Configuration;
importorg.springframework.web.servlet.config.annotation.DefaultServletHandlerConfigurer;
importorg.springframework.web.servlet.config.annotation.InterceptorRegistry;
importorg.springframework.web.servlet.config.annotation.ResourceHandlerRegistry;
importorg.springframework.web.servlet.config.annotation.WebMvcConfigurerAdapter;
@Configuration
publicclassWebConfigextendsWebMvcConfigurerAdapter{
publicstaticStringLOGIN_USER="loginUser";
publicWebConfig(){
super();
}
//因为新加了拦截器，这里需要重新设置资源地址
@Override
publicvoidaddResourceHandlers(ResourceHandlerRegistryregistry){
registry.addResourceHandler("/static/**").addResourceLocations(
"classpath:/static/");
registry.addResourceHandler("/templates/**").addResourceLocations(
"classpath:/templates/");
super.addResourceHandlers(registry);
}
@Override
publicvoidconfigureDefaultServletHandling(
DefaultServletHandlerConfigurerconfigurer){
configurer.enable();
}
@Override
publicvoidaddInterceptors(InterceptorRegistryregistry){
//拦截规则：除了login，其他都拦截判断,excludePathPatterns是排除拦截的路径，一个是登录验证地址，一个是登录页
registry.addInterceptor(new
LoginInterceptor()).addPathPatterns("/**").excludePathPatterns("/index","/system/user/validate");
super.addInterceptors(registry);
}
}
