尚硅谷 尚筹网项目后台管理系统的web.xml的替换

因为web.xml的经常会验证(validating)，动不动就卡住eclipse，因此决定把web.xml去掉

第一步在父项目中加入maven插件

    <build>
        <plugins>
            <plugin>
                <groupId>org.apache.maven.plugins</groupId>
                <artifactId>maven-war-plugin</artifactId>
                <version>3.0.0</version>
                <configuration>
                    <failOnMissingWebXml>false</failOnMissingWebXml>
                </configuration>
            </plugin>
        </plugins>
    </build>
        

第二步 创建几个配置类

RootConfig类代码 

package com.atguigu;

import org.springframework.context.annotation.Configuration;
import org.springframework.context.annotation.ImportResource;

@Configuration
@ImportResource(locations= {"classpath:spring-persist-*.xml"})
public class RootConfig {

}

WebConfig类代码

package com.atguigu;

import org.springframework.context.annotation.Configuration;
import org.springframework.context.annotation.ImportResource;

@Configuration
@ImportResource(locations= {"classpath:spring-web-mvc.xml"})
public class WebConfig {

}

WebApplication类代码

package com.atguigu;

import javax.servlet.Filter;

import org.springframework.web.filter.CharacterEncodingFilter;
import org.springframework.web.filter.DelegatingFilterProxy;
import org.springframework.web.servlet.support.AbstractAnnotationConfigDispatcherServletInitializer;

public class WebApplication extends AbstractAnnotationConfigDispatcherServletInitializer{

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

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

    @Override
    protected String[] getServletMappings() {
        return new String[] {"*.html","*.json"};
    }
    
    @Override
    protected Filter[] getServletFilters() {
        CharacterEncodingFilter characterEncodingFilter = new CharacterEncodingFilter();
        characterEncodingFilter.setEncoding("UTF-8");
        characterEncodingFilter.setForceEncoding(true);
        return new Filter[] {characterEncodingFilter};
    }


}

第三步 把web.xml删除就行

后面做project clean 与maven update 操作就行了
