ssm实现crud_创建项目（1）
1、创建maven项目
创建maven的java web空项目后配置maven的xml文件，需要的相关jar包信息可通过https://mvnrepository.com/进行搜索。配置文件完整内容如下：

beans>mybatis配置文件的编写：
<configuration>
<settings>
<setting name="mapUnderscoreToCamelCase" value="true"/>
settings>
<typeAliases>
<package name="cn.mk95.www.ssm_crud.bean"/>
typeAliases>
configuration>3、使用MyBatis逆向工程
在maven配置文件添加使用MyBatis逆向工程需要的jar包：
<dependency>
<groupId>org.mybatis.generatorgroupId>
<artifactId>mybatis-generator-coreartifactId>
<version>1.3.5version>
dependency>配置逆向需要的xml文件：
<generatorConfiguration>
<context id="DB2Tables" targetRuntime="MyBatis3">
<jdbcConnection driverClass="com.mysql.jdbc.Driver"
connectionURL="jdbc:mysql://localhost:3306/ssm_crud"
userId="yyh"
password="123456">
jdbcConnection>
<javaTypeResolver >
<property name="forceBigDecimals" value="false" />
javaTypeResolver>
<javaModelGenerator targetPackage="cn.mk95.www.ssm_crud.bean" targetProject=".\src\main\java">
<property name="enableSubPackages" value="true" />
<property name="trimStrings" value="true" />
javaModelGenerator>
<sqlMapGenerator targetPackage="mapper" targetProject=".\src\main\resources">
<property name="enableSubPackages" value="true" />
sqlMapGenerator>
<javaClientGenerator type="XMLMAPPER" targetPackage="cn.mk95.www.ssm_crud.dao" targetProject=".\src\main\java">
<property name="enableSubPackages" value="true" />
javaClientGenerator>
<table tableName="user" domainObjectName="User">table>
<table tableName="team" domainObjectName="Team">table>
context>
generatorConfiguration>
运行代码生成相关文件：
package cn.mk95.www.ssm_crud.test;
import org.mybatis.generator.api.MyBatisGenerator;
import org.mybatis.generator.config.Configuration;
import org.mybatis.generator.config.xml.ConfigurationParser;
import org.mybatis.generator.exception.InvalidConfigurationException;
import org.mybatis.generator.exception.XMLParserException;
import org.mybatis.generator.internal.DefaultShellCallback;
import java.io.File;
import java.io.IOException;
import java.sql.SQLException;
import java.util.ArrayList;
import java.util.List;
public class MbgTest {
public static void main(String[] args) {
List warnings = new ArrayList();
boolean overwrite = true;
File configFile = new File("mbg.xml");
ConfigurationParser cp = new ConfigurationParser(warnings);
Configuration config = null;
try {
config = cp.parseConfiguration(configFile);
} catch (IOException e) {
e.printStackTrace();
} catch (XMLParserException e) {
e.printStackTrace();
}
DefaultShellCallback callback = new DefaultShellCallback(overwrite);
MyBatisGenerator myBatisGenerator = null;
try {
myBatisGenerator = new MyBatisGenerator(config, callback, warnings);
} catch (InvalidConfigurationException e) {
e.printStackTrace();
}
try {
myBatisGenerator.generate(null);
} catch (SQLException e) {
e.printStackTrace();
} catch (IOException e) {
e.printStackTrace();
} catch (InterruptedException e) {
e.printStackTrace();
}
}
}
以上代码可通过mybatis generator官网查询。
