maven构建项目

在Eclipse下基于Maven整合Struts2，Spring和Mybatis3框架。

新建Maven project，type选择webapp

工程目录如下

---

这里我的jsp报错，解决办法：

右击项目，找到buildpath，点击Configure buildpath，如下图

点击Configure buildpath后出现下图

然后点击libraries，出现下图

点击add libraries 出现下图

点击next，出现下图后，选择你的web服务器

然后点击finish，就好了

修改pom.xml文件如下：

<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>com</groupId>    <artifactId>javaweb</artifactId>    <packaging>war</packaging>    <version>0.0.1-SNAPSHOT</version>    <name>javaweb Maven Webapp</name>    <url>http://maven.apache.org</url>    <properties>        <struts.version>2.3.28</struts.version>        <spring.version>3.0.5.RELEASE</spring.version>        <mybatis.version>3.2.6</mybatis.version>        <log4j.version>1.2.17</log4j.version>    </properties>    <dependencies>        <!-- struts包 -->        <dependency>            <groupId>org.apache.struts</groupId>            <artifactId>struts2-core</artifactId>            <version>${struts.version}</version>        </dependency>        <dependency>            <groupId>org.apache.struts</groupId>            <artifactId>struts2-spring-plugin</artifactId>            <version>${struts.version}</version>        </dependency>        <dependency>            <groupId>org.springframework</groupId>            <artifactId>spring-jdbc</artifactId>            <version>${spring.version}</version>        </dependency>        <!-- mybatis核心包 -->        <dependency>            <groupId>org.mybatis</groupId>            <artifactId>mybatis</artifactId>            <version>${mybatis.version}</version>        </dependency>        <!-- mybatis-spring包 -->        <dependency>            <groupId>org.mybatis</groupId>            <artifactId>mybatis-spring</artifactId>            <version>1.2.2</version>        </dependency>        <!-- java ee 包 -->        <dependency>            <groupId>javax</groupId>            <artifactId>javaee-api</artifactId>            <version>7.0</version>        </dependency>        <!-- Mysql数据库链接jar包 -->        <dependency>            <groupId>mysql</groupId>            <artifactId>mysql-connector-java</artifactId>            <version>5.1.30</version>        </dependency>        <dependency>            <groupId>commons-dbcp</groupId>            <artifactId>commons-dbcp</artifactId>            <version>1.2.2</version>        </dependency>        <dependency>            <groupId>junit</groupId>            <artifactId>junit</artifactId>            <version>3.8.1</version>            <scope>test</scope>        </dependency>    </dependencies>    <build>        <finalName>javaweb</finalName>    </build></project>

在resources目录下添加applicationContext.xml:

<?xml version="1.0" encoding="UTF-8"?><beans xmlns="http://www.springframework.org/schema/beans"    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:context="http://www.springframework.org/schema/context"    xsi:schemaLocation="        http://www.springframework.org/schema/beans        http://www.springframework.org/schema/beans/spring-beans-3.0.xsd        http://www.springframework.org/schema/context        http://www.springframework.org/schema/context/spring-context-3.0.xsd">    <!-- 配置要扫描的包 -->      <context:component-scan base-package="action"></context:component-scan>    <context:component-scan base-package="service.impl"></context:component-scan>      <!-- 指定数据源配置文件 -->    <context:property-placeholder location="classpath:jdbc.properties" />    <!-- 数据源 -->    <bean id="dataSource_dev" class="org.apache.commons.dbcp.BasicDataSource"        destroy-method="close">        <property name="driverClassName" value="${driver}" />        <property name="url" value="${url}" />        <property name="username" value="${username}" />        <property name="password" value="${password}" />    </bean>    <!-- 配置sqlSessionFactory -->    <bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean">        <property name="dataSource" ref="dataSource_dev" />        <property name="mapperLocations" value="classpath:mapper/*.xml" />    </bean>    <!-- 指定DAO层 -->    <bean class="org.mybatis.spring.mapper.MapperScannerConfigurer">        <property name="basePackage" value="dao" />        <property name="sqlSessionFactoryBeanName" value="sqlSessionFactory"></property>    </bean>    <!-- 使用Spring的事务管理器 -->    <bean id="transactionManager"        class="org.springframework.jdbc.datasource.DataSourceTransactionManager">        <property name="dataSource" ref="dataSource_dev" />    </bean></beans>

在resources目录下添加配置文件jdbc.properties（配置自己的数据库信息，用户名，密码）：

# JDBC Configuration  driver=com.mysql.jdbc.Driverurl=jdbc:mysql://localhost:3306/webusername=rootpassword=password# DBCP Pool settings  initialSize=0maxActive=20maxIdle=20minIdle=1maxWait=60000

在resources目录下添加struts配置文件struts.xml:

<?xml version="1.0" encoding="UTF-8" ?><!DOCTYPE struts PUBLIC "-//Apache Software Foundation//DTD Struts Configuration 2.1//EN" "http://struts.apache.org/dtds/struts-2.1.dtd"><struts>    <!-- 指定默认编码集 -->    <constant name="struts.i18n.encoding" value="UTF-8" />    <constant name="struts.multipart.maxSize" value="99000000" />    <constant name="struts.multipart.saveDir" value="/tmp"/>    <!-- 当struts配置文件修改时是否自动加载 -->    <constant name="struts.configuration.xmlreload" value="true" />    <!-- 开发模式下打印详细的错误信息 -->    <constant name="struts.devMode" value="true" />    <constant name="struts.ui.theme" value="xhtml" />    <include file="User.xml"></include></struts>

sources目录下添加mybatis配置文件mybatis-config.xml:

<?xml version="1.0" encoding="UTF-8" ?><!DOCTYPE configuration PUBLIC "-//mybatis.org//DTD Config 3.0//EN""http://mybatis.org/dtd/mybatis-3-config.dtd"><configuration>    <settings>        <setting name="cacheEnabled" value="true"/>        <setting name="lazyLoadingEnabled" value="true"/>        <setting name="aggressiveLazyLoading" value="true"/>    </settings>    <typeAliases>    </typeAliases></configuration>

在web.xml中添加如下配置：

<!-- spring的配置文件位置 -->    <context-param>        <param-name>contextConfigLocation</param-name>        <param-value>classpath:applicationContext.xml</param-value>    </context-param>    <!-- struts2过滤器配置 -->    <filter>        <filter-name>struts2</filter-name>        <filter-class>org.apache.struts2.dispatcher.ng.filter.StrutsPrepareAndExecuteFilter</filter-class>    </filter>    <filter-mapping>        <filter-name>struts2</filter-name>        <url-pattern>/*</url-pattern>    </filter-mapping>    <!-- 集成spring -->    <listener>        <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>    </listener>

在工程中添加如下类：

UserAction .java代码如下：

package action;import java.io.IOException;import java.io.PrintWriter;import java.util.List;import javax.annotation.Resource;import javax.servlet.http.HttpServletResponse;import org.apache.struts2.ServletActionContext;import org.springframework.context.annotation.Scope;import org.springframework.stereotype.Controller;import com.opensymphony.xwork2.ActionSupport;import beans.User;import service.IUserService;@Controller@Scope("prototype")public class UserAction extends ActionSupport {    private static final long serialVersionUID = 1L;    @Resource    private IUserService userService;    private User user;    private List<User> userlist;    public User getUser() {        return user;    }    public void setUser(User user) {        this.user = user;    }    public List<User> getUserlist() {        return userlist;    }    public void setUserlist(List<User> userlist) {        this.userlist = userlist;    }    public String execute() throws Exception {        System.out.println("execute");        return SUCCESS;    }    public String addUser() {        userService.addUser(user);        return SUCCESS;    }    public String deleteUser() {        userService.deleteUser(user.getId());        return SUCCESS;    }    public String queryAllUser() {        userlist = userService.queryAllUser();        return "list";    }    public void validate() {        System.out.println("validate()会对action中的所有方法进行校验");//        if(this.user.getName() == null || this.user.getName().trim().equals("")) {  //            this.addFieldError("name", "用户名不能为空！");  //        }      }     //直接返回一个字符串    public String queryUserNameByID() throws IOException{        HttpServletResponse response = ServletActionContext.getResponse();          response.setContentType("text/html;charset=UTF-8");        //response.sendError(401,"timeout");        PrintWriter out = response.getWriter();          out.println("luangeng123");//返回的字符串数据         out.flush();        out.close();        return null;      }}
