IDEA下搭建ssm项目-01

application-context.xml配置，这里的模板后面就不贴出了

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

   <!--这里直接 把其他配置分开-->
   <import resource="config/*.xml" />
</beans>

properties目录下

jdbc.properties：

driverClass=com.mysql.jdbc.Driver
jdbcUrl=jdbc:mysql://localhost:3306/你的数据库?characterEncoding=UTF-8
user=root
password=123456

接下来是config目录下的配置文件

annotation.xml：

<!--spring 扫包   @Service .....-->
<context:component-scan base-package="com.nelsoner">
   <!--不扫描 Controller -->
   <context:exclude-filter type="annotation" expression="org.springframework.stereotype.Controller"/>
</context:component-scan>

<!--自动装配-->
   <context:annotation-config/>

property.xml

<!-- 读取jdbc配置 -->
<!--这种方式的扩展性不好-->
<!--
   <context:property-placeholder location="classpath:properties/jdbc.properties" />
-->
<bean class="org.springframework.beans.factory.config.PropertyPlaceholderConfigurer">
   <property name="locations">
      <list>
         <!-- jdbc配置 -->
         <value>classpath:properties/jdbc.properties</value>
         <!-- memcached配置 -->
         
      </list>
   </property>
</bean>

jdbc.xml:

<!-- c3p0-->
<bean id="dataSource" class="com.mchange.v2.c3p0.ComboPooledDataSource">
   <property name="driverClass" value="${driverClass}"/>
   <property name="jdbcUrl" value="${jdbcUrl}"></property>
   <property name="user" value="${user}" />
   <property name="password" value="${password}"/>
</bean>

mybatis.xml：

<!--mybatis  sessionFactory配置-->
<bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean">
   <property name="dataSource" ref="dataSource"/>
   <!--这里要特别注意 classpath:com.nelsoner.core.dao/**/*.xml  /**/ 表示任意多级目录-->
   <property name="mapperLocations" value="classpath:com.nelsoner.core.dao/**/*.xml"/>
   <property name="typeAliasesPackage" value="com.nelsoner.core.bean"/>
</bean>

<!-- 扫包 --><bean class="org.mybatis.spring.mapper.MapperScannerConfigurer"> <property name="basePackage" value="com.nelsoner.core.dao"/></bean>

transation.xml：

<!-- spring 事务 -->
<bean id="transactionManager" class="org.springframework.jdbc.datasource.DataSourceTransactionManager">
   <property name="dataSource" ref="dataSource"/>
</bean>
<!-- 开启事务注解 -->
<tx:annotation-driven transaction-manager="transactionManager"/>

到这里基本配置完成

接下来写个测试

TestTb:

private Integer id;
private String name;
private Date birthday;  
//这里省略get set 

TestTbDao:

public interface TestTbDao {
   public void addTestTb(TestTb testTb);
}

TestTbService:

public interface TestTbService {
   public void addTestTb(TestTb testTb);
}

TestTbServiceImpl:

@Service
@Transactional
public class TestTbServiceImpl implements TestTbService{
   @Resource
   private TestTbDao testTbDao;
   public void addTestTb(TestTb testTb) {
      testTbDao.addTestTb(testTb);
   }
}

TestTbDao.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.nelsoner.core.dao.TestTbDao">
   <!--  添加测试数据  -->
   <!-- id 就是TestTbDao类的函数名-->
   <!--
      在mybatis.xml 中配置了如下： 所以 parameterType可以不写前面的包
      <property name="typeAliasesPackage" value="com.nelsoner.core.bean"/>
   -->
   <insert id="addTestTb" parameterType="TestTb">
      insert into test_tb
      (name,birthday)
      values
      (#{name},#{birthday})
   </insert>
</mapper>

接下来写测试方法

基于注解的Junit单元测试

TestTestTb:

@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration(locations = "classpath:application-context.xml")
public class TestTestTb{

   @Autowired
   private TestTbService testTbService;
   @Test
   public void testAdd() throws Exception {
      TestTb testTb = new TestTb();
      testTb.setName("金乐乐");
      
      testTbService.addTestTb(testTb);
   }
}
