java - 运行项目时项目中未检测到jsp

Question

我使用 spring security 有简单的登录屏幕。如果登录成功，则重定向到 home.jsp。但是，它说无法找到Jsp页面。在 maven 中创建新项目时，没有名为 webapp 的文件夹，因此我自己创建了该 webapp，并将该 webapp 添加到 webapp/WEB-INF/view/home.jsp 中，如下所示:

我的项目结构是:

因此，登录屏幕成功出现，当我登录时，会显示这样的消息:

它说找不到 home.jsp。

我的配置是::

package com.ashwin.security.config;

import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.ComponentScan;
import org.springframework.context.annotation.Configuration;
import org.springframework.web.servlet.ViewResolver;
import org.springframework.web.servlet.config.annotation.EnableWebMvc;
import org.springframework.web.servlet.view.InternalResourceViewResolver;

@Configuration
@EnableWebMvc
@ComponentScan(basePackages = "com.ashwin.security")
public class DemoAppConfig {

    @Bean
    public ViewResolver viewResolver() {
        InternalResourceViewResolver viewResolver=new InternalResourceViewResolver();
        viewResolver.setPrefix("/WEB-INF/view/");
        viewResolver.setSuffix(".jsp");
        return viewResolver;
    }



}

我的 pom.xml 是:

DispatcherServlet 类是

package com.ashwin.security.config;
import org.springframework.web.servlet.support.AbstractAnnotationConfigDispatcherServletInitializer;

public class SpringMvcDispatcherServletInitializer  extends AbstractAnnotationConfigDispatcherServletInitializer {


     @Override
        protected Class <?> [] getRootConfigClasses() {
            // TODO Auto-generated method stub
            return null;
        }

        @Override
        protected Class <?> [] getServletConfigClasses() {
            return new Class[] { DemoAppConfig.class  };
        }

        @Override
        protected String[] getServletMappings() {
            return new String[] { "/" };
        }

}

您的tomcat7-maven-plugin配置包含<path>/spring</path> 。请替换它并尝试使用 <path>/${project.build.finalName}</path> .
