Maven实战之搭建SSM项目

前言

在之前进行框架整合开发的时候，就深深感觉到每次的jar包的管理太过于麻烦，占用空间也大，在学习了Maven之后，便开始深深的爱上了这个神器，那么我就带着大家一起来实战搭建一下吧。

Maven搭建SSM开发环境

1. 新建Maven Web 项目

这里就不在多赘述了，不会的请参考我的上一篇文章Eclipse中Maven的使用以及Pom.xml详解

你新建好的web项目应该和下面一样：

2. 导入对应spring mvc、spring、mybatis的依赖包以及编写所需要的配置文件

（1）在项目的pom.xml文件中需要添加spring、springmvc、mybatis的依赖包：

project>

注意：因为我这里使用的c3p0数据库连接池和logback日志打印，所以也需要在pom文件中对应引入。

更新maven：项目右键->Maven->Update Project

（2）添加spring配置文件applicationContext.xml

<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.xsd
    http://www.springframework.org/schema/context
    http://www.springframework.org/schema/context/spring-context.xsd">     
    <context:component-scan base-package="com.mxf.service">context:component-scan>
    
    <context:property-placeholder location="classpath:db.properties" />

    
    <bean id="dataSource" class="com.mchange.v2.c3p0.ComboPooledDataSource">
        <property name="driverClass" value="${jdbc.mysql.driver}" />
        <property name="jdbcUrl" value="${jdbc.mysql.url}" />
        <property name="user" value="${jdbc.mysql.username}" />
        <property name="password" value="${jdbc.mysql.password}" />

        
        <property name="maxPoolSize" value="${jdbc.mysql.maxPoolSize}" />
        <property name="minPoolSize" value="${jdbc.mysql.minPoolSize}" />
        <property name="maxIdleTime" value="${jdbc.mysql.maxIdleTime}" />
        <property name="acquireIncrement" value="${jdbc.mysql.acquireIncrement}" />
        <property name="maxStatements" value="${jdbc.mysql.maxStatements}" />
        <property name="initialPoolSize" value="${jdbc.mysql.initialPoolSize}" />
    bean>
    
    
     
    <bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean">
        <property name="dataSource" ref="dataSource" />
        <property name="typeAliasesPackage" value="com.mxf.entity" />
        <property name="mapperLocations" value="classpath:com/mxf/mappers/*.xml">property>
    bean>
    
    <bean class="org.mybatis.spring.mapper.MapperScannerConfigurer">
        <property name="basePackage" value="com.mxf.mappers" />
        <property name="sqlSessionFactoryBeanName" value="sqlSessionFactory" />
    bean>
beans>

（3）添加springmvc配置文件springmvc.xml

<beans xmlns="http://www.springframework.org/schema/beans"
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xmlns:aop="http://www.springframework.org/schema/aop"
    xmlns:tx="http://www.springframework.org/schema/tx"
    xmlns:context="http://www.springframework.org/schema/context"
    xmlns:mvc="http://www.springframework.org/schema/mvc"
    xsi:schemaLocation="http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc-4.1.xsd
        http://www.springframework.org/schema/beans 
        http://www.springframework.org/schema/beans/spring-beans.xsd
        http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-4.1.xsd
        http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop-4.1.xsd
        http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-4.1.xsd
        http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx.xsd">
    
    <context:component-scan base-package="com.mxf.controller"/>
    <mvc:default-servlet-handler/>

    
    <mvc:annotation-driven />

    
    <bean class = "org.springframework.web.servlet.view.InternalResourceViewResolver">
          <property name="prefix" value="/WEB-INF/views/" />
          <property name="suffix" value=".jsp" />
      bean>
beans>

（4）配置数据库连接文件db.properties

jdbc.mysql.driver=com.mysql.jdbc.Driver
jdbc.mysql.url=jdbc:mysql://localhost:3306/first?useUnicode=true&characterEncoding=UTF-8
jdbc.mysql.username=root
jdbc.mysql.password=
jdbc.mysql.minPoolSize=2
jdbc.mysql.maxPoolSize=10
jdbc.mysql.maxIdleTime=1800000
jdbc.mysql.acquireIncrement=3
jdbc.mysql.maxStatements=1000
jdbc.mysql.initialPoolSize=3

（5）配置日志记录文件logback.xml

    
    <configuration info="true">    
            
        <property name="APP_NAME" value="moxiaofei" />
            
        <property name="LOG_HOME" value="F:\\MavenLog4j" />    
            
        <property name="ENCODER_PATTERN"    
           value="%d{yyyy-MM-dd  HH:mm:ss.SSS} [%thread] %-5level 类名:%logger{80} 方法名:%M 行号:%L- %msg%n" />    
        <contextName>${APP_NAME}contextName>    

            
        <appender name="STDOUT" class="ch.qos.logback.core.ConsoleAppender">    
            <encoder class="ch.qos.logback.classic.encoder.PatternLayoutEncoder">

        <appender name="FILE"    
            class="ch.qos.logback.core.rolling.RollingFileAppender">    
            <rollingPolicy class="ch.qos.logback.core.rolling.TimeBasedRollingPolicy">    
                <fileNamePattern>${LOG_HOME}/output.%d{yyyy-MM-dd}.logfileNamePattern>

        appender>    

            
        <appender name="ERROR_FILE"    
            class="ch.qos.logback.core.rolling.RollingFileAppender">

        appender>    

            
        <appender name="SYNC_FILE"  class="ch.qos.logback.core.rolling.RollingFileAppender">    
            <rollingPolicy class="ch.qos.logback.core.rolling.TimeBasedRollingPolicy">    
                <fileNamePattern>${LOG_HOME}/sync.%d{yyyy-MM-dd}.logfileNamePattern>    
                <maxHistory>30maxHistory>    
            rollingPolicy>    
            <encoder class="ch.qos.logback.classic.encoder.PatternLayoutEncoder">    
                <pattern>${ENCODER_PATTERN}pattern>    
            encoder>    
        appender>    

        <logger name="log.sync" level="INFO" addtivity="true">    
            <appender-ref ref="SYNC_FILE" />    
        logger>    

          
        <root level="INFO">    
            <appender-ref ref="STDOUT" />    
            <appender-ref ref="FILE" />    
            <appender-ref ref="ERROR_FILE" />    
        root>    
configuration>  

（6）配置项目目录下的web.xml文件：

<web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns="http://xmlns.jcp.org/xml/ns/javaee" xsi:schemaLocation="http://xmlns.jcp.org/xml/ns/javaee http://xmlns.jcp.org/xml/ns/javaee/web-app_3_1.xsd" id="WebApp_ID" version="3.1">

web-app>

3. 进行框架整合的测试

（1）按照上面配置文件中的配置对应创建相应的包：
- com.mxf.controller：控制层
- com.mxf.entity：实体类
- com.mxf.mappers：映射文件
- com.mxf.service：服务层
- com.mxf.service.impl：服务层实现类

（2）编写对应的类

完成后看起来应该会是下面这样：

Teacher.java

package com.mxf.entity;

public class Teacher {

    private Integer id;
    private String name;
    private String password;

    public Integer getId() {
        return id;
    }
    public void setId(Integer id) {
        this.id = id;
    }
    public String getName() {
        return name;
    }
    public void setName(String name) {
        this.name = name;
    }
    public String getPassword() {
        return password;
    }
    public void setPassword(String password) {
        this.password = password;
    }

}

ITeacherMapper.java

package com.mxf.mappers;

import java.util.List;

import com.mxf.entity.Teacher;

public interface ITeacherMapper {
    List getAllTeacherInfo();
}

TeacherMapper.xml

<mapper namespace="com.mxf.mappers.ITeacherMapper" >
  
  <select id="getAllTeacherInfo" resultType="com.mxf.entity.Teacher" >
     select id,name,password from teacher
  select>
mapper>

ITeacherServcie.java

package com.mxf.service;

import java.util.List;

import com.mxf.entity.Teacher;

public interface ITeacherServcie {
    List getAllTeacherInfo();
}

TeacherServiceImpl.java

package com.mxf.service.impl;

import java.util.List;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Service;

import com.mxf.entity.Teacher;
import com.mxf.mappers.ITeacherMapper;
import com.mxf.service.ITeacherServcie;

@Service("teacherService")
public class TeacherServiceImpl implements ITeacherServcie{

    @Autowired
    private ITeacherMapper teacherMapper;

    @Override
    public List getAllTeacherInfo() {
        return teacherMapper.getAllTeacherInfo();
    }

}

TeacherController.java

package com.mxf.controller;

import java.util.List;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Controller;
import org.springframework.ui.Model;
import org.springframework.web.bind.annotation.RequestMapping;

import com.mxf.entity.Teacher;
import com.mxf.service.ITeacherServcie;

@Controller
public class TeacherController {

    @Autowired
    private ITeacherServcie teacherServcie;

    @RequestMapping("/getAllTeacherInfo")
    public String getAllTeacherInfo(Model model){
        List list = teacherServcie.getAllTeacherInfo();
        model.addAttribute("list", list);
        return "teacher_info";
    }

}

WEB_INF/views/teacher_info.jsp

<%@page language="java" contentType="text/html; charset=UTF-8" pageEncoding="UTF-8"%>
<%@taglib uri="http://java.sun.com/jsp/jstl/core" prefix="c" %>

<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
<title>教师信息页面title>
head>
<body>
    <c:forEach items="${list }" var="teacher">
        <table>
            <tr>
                <td>id=${teacher.id }td>
                <td>name=${teacher.name }td>
                <td>password=${teacher.password }td>
            tr>
        table>
    c:forEach>
body>
html>

（3）进行测试

右键项目->Run As->Maven build…->->

输出栏没有任何错误信息输出，如下所示：

在浏览器中访问http://localhost:8080/Maven_SSM/getAllTeacherInfo，对应输出页面：
