警告o.s.web.servlet.PageNotFound - 找不到带URI的HTTP请求的映射

Question

添加Assets文件夹时出现此错误。 它为“assets”文件夹中包含的每个文件提供错误。

WARN  o.s.web.servlet.PageNotFound - No mapping found for HTTP request with URI [/assets/plugins/datepicker/datepicker3.css] in DispatcherServlet with name 'dispatcher'

这是Dispacther配置文件

package com.springmaven.config;

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


@Configuration
@EnableWebMvc
@ComponentScan({"com.springmaven.controller"})
public class DispatcherConfig {

    @Bean
    public InternalResourceViewResolver getInternalResourceViewResolver()
    {
        InternalResourceViewResolver internalResourceViewResolver=new InternalResourceViewResolver();
        internalResourceViewResolver.setPrefix("/WEB-INF/JSP/");
        internalResourceViewResolver.setSuffix(".jsp");
        return internalResourceViewResolver;
    }   
}

这是App Config

package com.springmaven.config;

import javax.servlet.ServletContext;
import javax.servlet.ServletException;
import javax.servlet.ServletRegistration;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.web.WebApplicationInitializer;
import org.springframework.web.context.ContextLoaderListener;
import org.springframework.web.context.support.AnnotationConfigWebApplicationContext;
import org.springframework.web.servlet.DispatcherServlet;

public class AppIntializer implements WebApplicationInitializer{


    @Autowired
    public void onStartup(ServletContext servletCon) throws ServletException {
        // TODO Auto-generated method stub
        AnnotationConfigWebApplicationContext rootContext = new AnnotationConfigWebApplicationContext();
        rootContext.register(ApplicationConfig.class);
        servletCon.addListener(new ContextLoaderListener(rootContext));

        AnnotationConfigWebApplicationContext servletConfig = new AnnotationConfigWebApplicationContext();
        servletConfig.register(DispatcherConfig.class);

        ServletRegistration.Dynamic registration = servletCon.addServlet("dispatcher", new DispatcherServlet(servletConfig));
        registration.setLoadOnStartup(1);
        registration.addMapping("/");
    }

}

这是安全配置

      }

    @Autowired
    public void configure(AuthenticationManagerBuilder auth) throws Exception {
         auth
         .authenticationProvider(customAuthenticationProvider);
    }


    @Override

                .usernameParameter("username").passwordParameter("password")     
                .and().csrf().csrfTokenRepository(csrfTokenRepository())
            .and()
                .logout().logoutSuccessUrl("/loginPage?logout"); 

    }

    @Bean

        return new SecurityEvaluationContextExtension();
    }

        HttpSessionCsrfTokenRepository repository = new HttpSessionCsrfTokenRepository(); 
        repository.setSessionAttributeName("_csrf");
        return repository; 
    }
}

您需要添加对静态网络资源的支持。

要将其配置为由Spring管理，请参阅this question。
