Maven實戰(zhàn)之搭建SSM項目

前言

在之前進行框架整合開發(fā)的時候，就深深感覺到每次的jar包的管理太過于麻煩，占用空間也大，在學習了Maven之后，便開始深深的愛上了這個神器，那么我就帶著大家一起來實戰(zhàn)搭建一下吧。

Maven搭建SSM開發(fā)環(huán)境

1. 新建Maven Web 項目

這里就不在多贅述了，不會的請參考我的上一篇文章Eclipse中Maven的使用以及Pom.xml詳解

你新建好的web項目應該和下面一樣：

web項目

2. 導入對應spring mvc、spring、mybatis的依賴包以及編寫所需要的配置文件

（1）在項目的pom.xml文件中需要添加spring、springmvc、mybatis的依賴包：

<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/xsd/maven-4.0.0.xsd">

  </dependencies>
</project>

注意：因為我這里使用的c3p0數據庫連接池和logback日志打印，所以也需要在pom文件中對應引入。

（2）添加spring配置文件applicationContext.xml

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"

        <property name="initialPoolSize" value="${jdbc.mysql.initialPoolSize}" />
    </bean>
    <!--聲明式事務管理  -->
    <!-- 給mybatis注入數據源 并創(chuàng)建對應對象 -->
    <!-- spring和MyBatis完美整合，不需要mybatis的配置映射文件 --> 
    <bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean">

        <property name="basePackage" value="com.mxf.mappers" />
        <property name="sqlSessionFactoryBeanName" value="sqlSessionFactory" />
    </bean>
</beans>

（2）添加springmvc配置文件springmvc.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"

    <!-- 設置組件掃描的基礎包 -->
    <context:component-scan base-package="com.mxf.controller"/>
    <mvc:default-servlet-handler/>
    
    <!-- 開啟注解 -->
    <mvc:annotation-driven />
    
    <!-- 配置視圖解析器 -->
    <bean class = "org.springframework.web.servlet.view.InternalResourceViewResolver">
          <property name="prefix" value="/WEB-INF/views/" />
          <property name="suffix" value=".jsp" />
      </bean>
</beans>

（3）配置數據庫連接文件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

（4）配置日志記錄文件logback.xml

<?xml version="1.0" encoding="UTF-8"?>    
    <configuration info="true">    
        <!-- 應用名稱 -->    
        <property name="APP_NAME" value="moxiaofei" />
        <!--日志文件的保存路徑,首先查找系統(tǒng)屬性-Dlog.dir,如果存在就使用其；否則，在當前目錄下創(chuàng)建名為logs目錄做日志存放的目錄 -->

        <contextName>${APP_NAME}</contextName>    
        
        <!-- 控制臺日志：輸出全部日志到控制臺 -->    
        <appender name="STDOUT" class="ch.qos.logback.core.ConsoleAppender">    
            <encoder class="ch.qos.logback.classic.encoder.PatternLayoutEncoder">    
                <Pattern>${ENCODER_PATTERN}</Pattern>    
            </encoder>    
        </appender>    
        
       
        <!-- 文件日志：輸出全部日志到文件 -->    
        <appender name="FILE"

                <fileNamePattern>${LOG_HOME}/output.%d{yyyy-MM-dd}.log</fileNamePattern>  
                <!-- 保存30天日志文件   -->  
                <maxHistory>30</maxHistory>    
            </rollingPolicy>    
            <encoder class="ch.qos.logback.classic.encoder.PatternLayoutEncoder">

            </encoder>    
        </appender>    
        
        <!-- 錯誤日志：用于將錯誤日志輸出到獨立文件 -->    
        <appender name="ERROR_FILE"    
            class="ch.qos.logback.core.rolling.RollingFileAppender">    
            <rollingPolicy class="ch.qos.logback.core.rolling.TimeBasedRollingPolicy">

                <pattern>${ENCODER_PATTERN}</pattern>    
            </encoder>    
            <filter class="ch.qos.logback.classic.filter.ThresholdFilter">    
                <level>WARN</level>    
            </filter>    
        </appender>    
            
        <!-- 獨立輸出的同步日志 -->    
        <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}.log</fileNamePattern>

                <pattern>${ENCODER_PATTERN}</pattern>    
            </encoder>    
        </appender>    
            
        <logger name="log.sync" level="INFO" addtivity="true">    
            <appender-ref ref="SYNC_FILE" />    
        </logger>    
          
        <!-- 全局輸出的方式 -->  
        <root level="INFO">

            <appender-ref ref="ERROR_FILE" />    
        </root>    
</configuration>

（5）配置項目目錄下的web.xml文件：

<?xml version="1.0" encoding="UTF-8"?>
<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">

  </servlet>
  <servlet-mapping>
    <servlet-name>springDispatcherServlet</servlet-name>
    <url-pattern>/</url-pattern>
  </servlet-mapping>
</web-app>

3. 進行框架整合的測試

（1）按照上面配置文件中的配置對應創(chuàng)建相應的包：

  • com.mxf.controller：控制層
  • com.mxf.entity：實體類
  • com.mxf.mappers：映射文件
  • com.mxf.service：服務層
  • com.mxf.service.impl：服務層實現類
創(chuàng)建所有的包

（2）編寫對應的類

完成后看起來應該會是下面這樣：

編碼

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<Teacher> getAllTeacherInfo();
}

TeacherMapper.xml

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE mapper PUBLIC "-//mybatis.org//DTD Mapper 3.0//EN" "http://mybatis.org/dtd/mybatis-3-mapper.dtd" >
<mapper namespace="com.mxf.mappers.ITeacherMapper" >
  <!-- 查詢所有簡歷信息 -->
  <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<Teacher> 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<Teacher> 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<Teacher> list = teacherServcie.getAllTeacherInfo();
        model.addAttribute("list", list);
        return "teacher_info";
    }
    
}

WEB_INF/views/teacher_info.jsp
