　　　　2）修改Source Folder的编译路径，进入Java Build Bath窗口，双击每个文件夹下的Output folder，指定路径。

　　　　　src/main/java和src/main/resource指定target/calsses，

　　　　　src/test/java和src/test/resource指定target/test-classes

　　　　　都选上选上Allow output folders for source folders.

　　3、把项目转为 Dynamic Web Module

　　　　1）在项目上点击右键，选择属性，然后选择Project facets，然后点击Convert to faceted form...

　　　勾选Dynamic Web Module，选择3.0，表示支持servlet3.0

　　　勾选Java，选择1.6或更高的jdk版本

　　　　2）配置部署的程序Deployment Assembly，删掉test的那两项，test的程序发布的时候不需要，添加maven的依赖库，Eclipse发布的时候可以发布到lib目录中

　　　　3）删除jdk5,添加jdk6

　　4、pom.xml文件配置，添加Servlet3依赖、日志配置等

<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"  xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/maven-v4_0_0.xsd">  <modelVersion>4.0.0</modelVersion>  <groupId>cn.luxh.app</groupId>  <artifactId>app</artifactId>  <packaging>war</packaging>  <version>0.0.1-SNAPSHOT</version>  <name>app Maven Webapp</name>  <url>http://maven.apache.org</url>  <!-- 属性配置 -->  <properties>      <project.build.sourceEncoding>UTF-8</project.build.sourceEncoding>      <junit.version>4.10</junit.version>      <logback.version>1.0.7</logback.version>      <slf4j.version>1.7.2</slf4j.version>  </properties>    <!-- 依赖配置 -->  <dependencies>       <dependency>         <groupId>junit</groupId>         <artifactId>junit</artifactId>         <version>${junit.version}</version>         <scope>test</scope>    </dependency>    <dependency>        <groupId>javax.servlet</groupId>        <artifactId>javax.servlet-api</artifactId>        <version>3.1-b02</version>        <type>jar</type>        <scope>provided</scope>    </dependency>    <dependency>        <groupId>org.slf4j</groupId>        <artifactId>slf4j-api</artifactId>        <version>${slf4j.version}</version>    </dependency>    <dependency>        <groupId>ch.qos.logback</groupId>        <artifactId>logback-core</artifactId>        <version>${logback.version}</version>    </dependency>    <dependency>        <groupId>ch.qos.logback</groupId>        <artifactId>logback-classic</artifactId>        <version>${logback.version}</version>    </dependency>  </dependencies>  <build>    <finalName>demo</finalName>    <plugins>        <plugin>            <groupId>org.apache.maven.plugins</groupId>            <artifactId>maven-compiler-plugin</artifactId>            <version>2.5.1</version>            <configuration>                <source>1.6</source>                    <target>1.6</target>              </configuration>        </plugin>    </plugins>  </build></project>

　　5、logback.xml日志文件配置，该文件存放在src/main/resources/目录下

<?xml version="1.0" encoding="UTF-8"?><configuration>   <!-- 控制台输出 -->  <appender name="stdout" class="ch.qos.logback.core.ConsoleAppender">      <encoder>          <pattern>%date [%thread] %-5level %logger{80} - %msg%n</pattern>      </encoder>  </appender>  <root level="INFO">      <appender-ref ref="stdout"/>  </root></configuration>

　　6、编写Servlet

　　　　1）写个编码过滤器

package cn.luxh.app.filter;import java.io.IOException;import javax.servlet.Filter;import javax.servlet.FilterChain;import javax.servlet.FilterConfig;import javax.servlet.ServletException;import javax.servlet.ServletRequest;import javax.servlet.ServletResponse;import javax.servlet.annotation.WebFilter;import org.slf4j.Logger;import org.slf4j.LoggerFactory;/** * Servlet Filter implementation class EncodingFilter */@WebFilter("/EncodingFilter")public class EncodingFilter implements Filter {        final static Logger LOG = LoggerFactory.getLogger(EncodingFilter.class);    public void destroy() {        LOG.info("销毁......");    }    public void doFilter(ServletRequest request, ServletResponse response, FilterChain chain) throws IOException, ServletException {        request.setCharacterEncoding("UTF-8");        response.setCharacterEncoding("UTF-8");        chain.doFilter(request, response);    }    public void init(FilterConfig fConfig) throws ServletException {        LOG.info("初始化......");    }}

　　　　2）第一个Servlet

package cn.luxh.app.servlet;import java.io.IOException;import java.io.PrintWriter;import javax.servlet.ServletException;import javax.servlet.annotation.WebServlet;import javax.servlet.http.HttpServlet;import javax.servlet.http.HttpServletRequest;import javax.servlet.http.HttpServletResponse;import org.slf4j.Logger;import org.slf4j.LoggerFactory;/** * Servlet implementation class FirstServlet */@WebServlet("/FirstServlet")public class FirstServlet extends HttpServlet {        final static Logger LOG = LoggerFactory.getLogger(FirstServlet.class);        private static final long serialVersionUID = 6833688147345340845L;    protected void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {        LOG.info("hello");        PrintWriter out = response.getWriter();        out.print("first servlet");        out.flush();        out.close();            }}
