每當我運行我的項目時,它都不會將welcome.page顯示為首頁,這表明找不到資源
您可以在web.xml文件中添加以下代碼。
<welcome-file-list>
<welcome-file>welcome.jsp</welcome-file>
</welcome-file-list>
除了先前的Sachin Aryal答案之外,您還可以添加更多歡迎頁面。
<welcome-file-list> <welcome-file>welcome.jsp</welcome-file> <welcome-file>firstpage.html</welcome-file> <welcome-file>first.jsp</welcome-file> </welcome-file-list>
第一個可用文件將作為歡迎文件
如我所見,您正在使用Javaconfig,即沒有xml方法。 我將建議您這樣做1)創建一個根配置類,即
@Configuration
@ComponentScan({ "com.myrootpackage.whatsoever" })
public class RootClass{
}
2)設置您已經擁有的類,即LoginApplication配置以擴展WebMvcConfigurerAdapter,這將使您也可以加載資源或將來可能具有任何css或js的任何文件夾
Class LoginApplication extends WebMvcConfigurerAdapter {
@Override
public void addResourceHandlers(ResourceHandlerRegistry registry) {
registry.addResourceHandler("/resources/**")
.addResourceLocations("/resources/");
//your view resolver bean as you already have above goes here.
}}
3)現在在您已經擁有的webApplicationInitializer類中,請注意以下幾點
@Override
protected Class<?>[] getRootConfigClasses() {
return new Class[] { RootClass.class };
}
@Override
protected Class<?>[] getServletConfigClasses() {
return class[]{LoginApplication.class];
}
最后,確保該應用程序運行時,您應該具有Locahlhost:yourport,並且沒有其他任何內容可以看到welcome.jsp頁面,並確保welcome.jsp頁面位於WEB-INF / views中。 希望這可以幫助。
