个人网站搭建第一部分——使用maven创建SSM项目

Maven+Eclipse+SpringMvc+Spring+Mybatis项目搭建

（1）选择Maven Project

（2）点击Next，选择默认工作空间位置

（3）选择Web类型

（4）填写GroupID、ArtifactID（GroupId两段组成[域+公司名称]相当于一个组织,ArtifactID对应项目名称）

（5）设置默认Server服务器和JDK版本

右键项目 --> Properties --> Server --> 选择Tomcat

右键项目 --> Properties --> Java Build Path --> 选择Tomcat和JDK的包导入

（6）修改pom.xml导入SSM框架所需的包(以下为我的pom.xml,可直接替换)

（7）完善项目结构

右键项目 --> Source folder --> 添加src/test/resources和src/main/resources,这里由于我有，所以提示

添加完成后,完整的项目结构

 移除不必要的文件夹

（8）创建项目用的配置文件（推荐使用UTF-8编码）

jdbc.properties
log4j.properties
mybatis-config.xml
spring-mvc.xml
spring-mybatis.xml

这些文件后面还会修改，这里先不贴了，有兴趣看后面章节

（9）Mysql数据库

#创建数据库
CREATE DATABASE ssm_database;
#创建数据库表（先删后插）
DROP TABLE IF EXISTS `tb_user`;
CREATE TABLE tb_user(
    userid int primary key auto_increment,
    username VARCHAR(200),
    userpassword VARCHAR(200),
    createdate TIMESTAMP
);

（10）根据Mybatis自动生成(使用maven插件)

pom.xml增加配置

<!-- MyBatis代码自动生成 -->
<plugin>
    <groupId>org.mybatis.generator</groupId>
    <artifactId>mybatis-generator-maven-plugin</artifactId>
    <version>1.3.2</version>
    <dependencies>
        <dependency>
            <groupId>mysql</groupId>
            <artifactId>mysql-connector-java</artifactId>
            <version>5.1.35</version>
        </dependency>
    </dependencies>
    <configuration>
         <!--配置文件的路径-->
         <configurationFile>${basedir}/src/main/resources/generatorConfig.xml</configurationFile> 
        <overwrite>true</overwrite>
    </configuration>
</plugin>

创建generatorConfig.xml配置文件

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE generatorConfiguration
  PUBLIC "-//mybatis.org//DTD MyBatis Generator Configuration 1.0//EN"
  "http://mybatis.org/dtd/mybatis-generator-config_1_0.dtd">
<generatorConfiguration>
    <context id="cn.zzy" targetRuntime="MyBatis3">
        <plugin type="org.mybatis.generator.plugins.EqualsHashCodePlugin"></plugin>  
        <plugin type="org.mybatis.generator.plugins.SerializablePlugin"></plugin> 
         <plugin type="org.mybatis.generator.plugins.ToStringPlugin"></plugin> 
        <commentGenerator>
            <!-- 这个元素用来去除指定生成的注释中是否包含生成的日期 false:表示保护 -->
            <!-- 如果生成日期，会造成即使修改一个字段，整个实体类所有属性都会发生变化，不利于版本控制，所以设置为true -->
            <property name="suppressDate" value="true" />
            <!-- 是否去除自动生成的注释 true：是 ： false:否 -->
            <property name="suppressAllComments" value="false" />
        </commentGenerator>
        <!--数据库链接URL，用户名、密码 -->
        <jdbcConnection driverClass="com.mysql.jdbc.Driver"
            connectionURL="jdbc:mysql://localhost/ssm_database" userId="root" password="root">
            </jdbcConnection>
        <javaTypeResolver>
            <!-- This property is used to specify whether MyBatis Generator should 
                force the use of java.math.BigDecimal for DECIMAL and NUMERIC fields, -->
            <property name="forceBigDecimals" value="false" />
        </javaTypeResolver>
        <!-- 生成模型的包名和位置 -->
        <javaModelGenerator targetPackage="com.cn.zzy.model"
            targetProject="target">
            <property name="enableSubPackages" value="true" />
            <property name="trimStrings" value="true" />
        </javaModelGenerator>
        <!-- 生成映射文件的包名和位置 -->
        <sqlMapGenerator targetPackage="com.cn.zzy.mapping"
            targetProject="target">
            <property name="enableSubPackages" value="true" />
        </sqlMapGenerator>
        <!-- 生成DAO的包名和位置 -->
        <javaClientGenerator type="XMLMAPPER"
            targetPackage="com.cn.zzy.dao" implementationPackage="com.cn.zzy.dao.impl"  targetProject="target">
            <property name="enableSubPackages" value="true" />
        </javaClientGenerator>
        
        <!-- 要生成哪些表 -->
        <table tableName="tb_user" domainObjectName="user"
            enableCountByExample="false" enableUpdateByExample="false"
            enableDeleteByExample="false" enableSelectByExample="false"
            selectByExampleQueryId="false"></table>
    </context>
</generatorConfiguration>

生成后文件会在target目录下，需要手动复制到src/main/java目录下

右键pom.xml文件 --> Run As --> maven Build …… --> 在goals输入：mybatis-generator:generate 即可自动生成

 遇到问题罗列：

（1）org.apache.maven.archiver.MavenArchiver.getManifest(org.apache.maven.project.MavenProject, org.apache.maven.archiver.MavenArchiveConfiguration)

解决：

Help --> Install New SoftWare --> Add

name:MavenArchiver

Location:https://otto.takari.io/content/sites/m2e.extras/m2eclipse-mavenarchiver/0.17.2/N/LATEST/

由于是国内的,速度有点慢,大概5-10分钟,重启Eclipse，问题解决

（2）Project configuration is not up-to-date with pom.xml. Run Maven->Update Project or use Quick Fix

解决：

右键项目 --> maven --> update Project，问题解决

（3）Build path specifies execution environment JavaSE-1.8. There are no compatible JREs installed in the workspace

 解决：

右键项目 --> Java Build Path --> 重新加入JDK
