5.2 工程依赖结构
5.3 环境搭建
搭建 mybatis 环境
搭建 springioc 环境
整合 mybatis和spring
搭建 springioc 环境
整合
1.创建 export_parent 父工程（打包方式选择 pom）
删除src目录-在pom文件中带入依赖
2.创建 export_web_manager 子模块（打包方式是 war 包）
3.创建 export_service_system 子模块（打包方式是 jar 包）
4.创建 export_domain 子模块（打包方式是 jar 包）
5.创建 export_dao 子模块（打包方式是 jar 包）
6.创建 export_common 子模块（打包方式是 jar 包）
环境搭建步骤如下:
<1> 在 export_domain 子模块创建实体类Company(和数据库中的表对应)
<2> 在 export_dao 子模块创建CompanyDao接口
<3> 在 export_dao 子模块的Resources目录下创建CompanyDao.xml配置文件
<4> 在 export_service_system 子模块创建CompanyService接口
<5>在 export_service_system 子模块创建CompanyService接口的实现类CompanyServiceImpl
<6>在 export_service_system 子模块的Resources的目录下创建applicationContext-service.xml配置文件
<!--包扫描：开启注解支持-->
<context:component-scan base-package="cn.itcast.service"></context:component-scan>
<7>在 export_service_system 子模块的test的目录下创建CompanyServiceText测试类
package cn.itcast.test;
import cn.itcast.domain.company.Company;
import cn.itcast.service.company.CompanyService;
import org.junit.Test;
import org.junit.runner.RunWith;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.test.context.ContextConfiguration;
import org.springframework.test.context.junit4.SpringJUnit4ClassRunner;
import java.util.List;
@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration(locations = "classpath*:spring/applicationContext-*.xml")
public class CompanyServiceTest {
@Autowired
private CompanyService companyService;
@Test
public void testFindAll() {
List<Company> list = companyService.findAll();
for (Company company : list) {
System.out.println(company);
}
}
}
<8>整合mybatis和springioc
在 export_service_system 子模块的Resources的目录下的applicationContext-service.xml中添加事务
<!--事务配置：xml配置-->
<!--1.创建事务管理器-->
<bean id="transactionManager" class="org.springframework.jdbc.datasource.DataSourceTransactionManager">
<property name="dataSource" ref="dataSource"></property>
</bean>
<!--2.事务通知-->
<tx:advice id="txAdvice" transaction-manager="transactionManager">
<tx:attributes>
<!--service层方法对事务的支持配置-->
<tx:method name="find*" read-only="true" propagation="SUPPORTS"/>
<tx:method name="save*" read-only="false" propagation="REQUIRED"/>
<tx:method name="update*"/>
<tx:method name="delete*"/>
<tx:method name="*"/>
</tx:attributes>
</tx:advice>
<!--3.配置事务AOP-->
<aop:config>
<aop:pointcut id="pt" expression="execution(* cn.itcast.service.*.impl.*.*(..))"></aop:pointcut>
<aop:advisor advice-ref="txAdvice" pointcut-ref="pt"></aop:advisor>
</aop:config>
<9>测试mybatis和springioc是否整合成功
<10> 在export_web_manager 子模块内创建CompanyController
<11> 在export_web_manager 子模块内创建springmvc.xml配置文件
<12> 在export_web_manager 子模块内修改web.xml配置文件
<web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xmlns="http://java.sun.com/xml/ns/javaee"
xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd"

<13>修改CompanyController
<14> 添加company-list.jsp页面
<15> 部署tomcat
并对tomcat起别名
<16> 日期转换器
修改export_web_manager 子模块内springmvc.xml配置文件
<17> 异常处理

7. 日期与统一异常处理
7.1 日期处理
/**
* 自定义类型转化器
* 实现Converter接口
*/
public class StringToDateConverter implements Converter<String,Date> {
@Override
public Date convert(String source) {
Date date = null;
try {
date = new SimpleDateFormat("yyyy-MM-dd").parse(source);
}catch (Exception e) {
e.printStackTrace();
}
return date;
}
}
配置
<bean id="conversionService" class="org.springframework.context.support.ConversionServiceFactoryBean">
<property name="converters">
<set>
<bean class="cn.itcast.web.converter.StringToDateConverter"></bean>
</set>
</property>
</bean>
<mvc:annotation-driven conversion-service="conversionService"></mvc:annotation-driven>
7.2 异常处理
/**
* 统一异常处理
* 实现接口：HandlerExceptionResolver
*/
@Component
public class CustomExceptionResolver implements HandlerExceptionResolver {
/**
* 1.配置错误信息
* 2.跳转错误页面
*/
@Override
public ModelAndView resolveException(HttpServletRequest request, HttpServletResponse response, Object handler, Exception ex) {
ex.printStackTrace();
ModelAndView mv = new ModelAndView();
mv.setViewName("error");
mv.addObject("errorMsg","对不起，我错了");
mv.addObject("ex",ex);
return mv;
}
}
