個人網站搭建第一部分——使用maven創建SSM項目

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

（1）選擇Maven Project

（2）點擊Next，選擇默認工作空間位置

 

（3）選擇Web類型

（4）填寫GroupID、ArtifactID（GroupId兩段組成[域+公司名稱]相當於一個組織,ArtifactID對應項目名稱）

（5）設置默認Server服務器和JDK版本

右鍵項目 --> Properties --> Server --> 選擇Tomcat

右鍵項目 --> Properties --> Java Build Path --> 選擇Tomcat和JDK的包導入

（6）修改pom.xml導入SSM框架所需的包(以下為我的pom.xml,可直接替換)

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

          <version>3.0.0</version>

（7）完善項目結構

右鍵項目 --> Source folder --> 添加src/test/resources和src/main/resources,這里由於我有，所以提示

添加完成后,完整的項目結構

 

 移除不必要的文件夾

（8）創建項目用的配置文件（推薦使用UTF-8編碼）

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

這些文件后面還會修改，這里先不貼了，有興趣看后面章節

（9）Mysql數據庫

#創建數據庫
CREATE DATABASE ssm_database;
#創建數據庫表（先刪后插）
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）根據Mybatis自動生成(使用maven插件)

pom.xml增加配置

<!-- MyBatis代碼自動生成 -->
<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>
         <!--配置文件的路徑-->
         <configurationFile>${basedir}/src/main/resources/generatorConfig.xml</configurationFile> 
        <overwrite>true</overwrite>
    </configuration>
</plugin>

創建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>
            <!-- 這個元素用來去除指定生成的注釋中是否包含生成的日期 false:表示保護 -->
            <!-- 如果生成日期，會造成即使修改一個字段，整個實體類所有屬性都會發生變化，不利於版本控制，所以設置為true -->
            <property name="suppressDate" value="true" />
            <!-- 是否去除自動生成的注釋 true：是 ： false:否 -->
            <property name="suppressAllComments" value="false" />
        </commentGenerator>
        <!--數據庫鏈接URL，用戶名、密碼 -->
        <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>

生成后文件會在target目錄下，需要手動復制到src/main/java目錄下

右鍵pom.xml文件 --> Run As --> maven Build …… --> 在goals輸入：mybatis-generator:generate 即可自動生成

 遇到問題羅列：

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

解決：

Help --> Install New SoftWare --> Add

name:MavenArchiver

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

由於是國內的,速度有點慢,大概5-10分鍾,重啟Eclipse，問題解決

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

解決：

右鍵項目 --> maven --> update Project，問題解決

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

 

 解決：

右鍵項目 --> Java Build Path --> 重新加入JDK
