spring4.0全注解配置的应用，以及一些我平时写项目的一些常用配置

package com.travelsky.autotest.config.spring;

import java.util.EnumSet;

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

import org.springframework.web.WebApplicationInitializer;
import org.springframework.web.context.ContextLoaderListener;
import org.springframework.web.context.support.AnnotationConfigWebApplicationContext;
import org.springframework.web.filter.CharacterEncodingFilter;
import org.springframework.web.servlet.DispatcherServlet;

import com.travelsky.autotest.aop.RequestFilter;

public class WebInit implements WebApplicationInitializer {
    @Override
    public void onStartup(ServletContext sc) throws ServletException {
        // Create the ‘root‘ Spring application context
        AnnotationConfigWebApplicationContext application = new AnnotationConfigWebApplicationContext();
        application.scan("com.travelsky.autotest.config.spring");//扫描配置文件
        // Manages the lifecycle of the root application context
        sc.addListener(new ContextLoaderListener(application));//把配置文件添加到WEB容器里面，相当于去读取了XXX.servlet.XML 文件
        //CharacterEncodingFilter 
        CharacterEncodingFilter characterEncodingFilter = new CharacterEncodingFilter();
        characterEncodingFilter.setEncoding("UTF-8");
        characterEncodingFilter.setForceEncoding(true);
        FilterRegistration filterRegistration = sc.addFilter("characterEncodingFilter", characterEncodingFilter);
        filterRegistration.addMappingForUrlPatterns(EnumSet.of(DispatcherType.REQUEST), false, "/*");//

        sc.addFilter("requestFilter", RequestFilter.class).addMappingForUrlPatterns(EnumSet.of(DispatcherType.REQUEST), false, "/case/*");//过滤路径 添加过滤器

        
        
        AnnotationConfigWebApplicationContext webContext = new AnnotationConfigWebApplicationContext();
        ServletRegistration.Dynamic appServlet = sc.addServlet("appServlet", new DispatcherServlet(webContext));//配置dispatchservlet
        appServlet.setLoadOnStartup(1);//貌似只有1,0或者-1
        appServlet.addMapping("/"); //配置请求的匹配方式
    }

}
