基于Spring java的配置-无法打开ServletContext资源

Question

我正在为一个项目使用完全基于java的配置。

部署webapp时，我得到以下错误：

问题是我不明白为什么Spring在我注册类配置时尝试加载XML配置：

WebappInitializer：

package net.brewspberry.util.config;

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

import net.brewspberry.filters.AuthentificationFilter;

import org.springframework.context.annotation.Bean;
import org.springframework.web.WebApplicationInitializer;
import org.springframework.web.context.ContextLoaderListener;
import org.springframework.web.context.support.AnnotationConfigWebApplicationContext;
import org.springframework.web.servlet.DispatcherServlet;
import org.springframework.web.servlet.support.AbstractAnnotationConfigDispatcherServletInitializer;

public class SpringWebappInitializer extends
        AbstractAnnotationConfigDispatcherServletInitializer implements
        WebApplicationInitializer {

    public void onStartup(ServletContext servletContext)
            throws ServletException {

        AnnotationConfigWebApplicationContext rootContext = new AnnotationConfigWebApplicationContext();

        rootContext.setServletContext(servletContext);

        // rootContext.setConfigLocation("net.brewspberry.util");

        rootContext.register(SpringCoreConfiguration.class);

        servletContext.addListener(new ContextLoaderListener(rootContext));

        // now the config for the Dispatcher servlet
        AnnotationConfigWebApplicationContext mvcContext = new     AnnotationConfigWebApplicationContext();
    // mvcContext.setConfigLocation("net.brewspberry.util.config");
    //mvcContext.register(SpringWebappConfiguration.class);


    ServletRegistration.Dynamic dispatcher = servletContext.addServlet(
            "DispatcherServlet", new DispatcherServlet(mvcContext));

    dispatcher.setLoadOnStartup(1);
    dispatcher.addMapping("*.do");

}




@Override
protected Filter[] getServletFilters() {
    return null; // new Filter[] { new AuthentificationFilter() };

}

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

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

@Override
protected String[] getServletMappings() {
    // TODO Auto-generated method stub
    return null;
}

}

Webapp配置：

package net.brewspberry.util.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.DefaultServletHandlerConfigurer;
import org.springframework.web.servlet.config.annotation.EnableWebMvc;
import org.springframework.web.servlet.config.annotation.ResourceHandlerRegistry;
import org.springframework.web.servlet.config.annotation.ViewControllerRegistry;
import org.springframework.web.servlet.config.annotation.WebMvcConfigurerAdapter;
import org.springframework.web.servlet.view.InternalResourceViewResolver;

@Configuration
@EnableWebMvc
@ComponentScan({ "net.brewspberry" })
public class SpringWebappConfiguration extends WebMvcConfigurerAdapter {

    @Override
    public void configureDefaultServletHandling(
            DefaultServletHandlerConfigurer configurer) {
        configurer.enable();
    }

    @Override
    public void addResourceHandlers(ResourceHandlerRegistry registry) {
        registry.addResourceHandler("/resources/**").addResourceLocations("/resources/");
    }

    @Override
    public void addViewControllers(ViewControllerRegistry registry) {
        registry.addViewController("/").setViewName("forward:/login.jsp");
    }

    @Bean(name = "viewResolver")
    public InternalResourceViewResolver getViewResolver() {
        InternalResourceViewResolver viewResolver = new InternalResourceViewResolver();
        viewResolver.setPrefix("/");
        viewResolver.setSuffix(".jsp");
        return viewResolver;
    }

}

        mvcContext.register(SpringWebappConfiguration.class);

知道吗？

您必须指定dispatcher servlet以使用SpringWebappConfiguration作为it上下文，或者将SpringWebappConfiguration设置为applicationRoot上下文。
