spring boot 学习--08---搭建ssmm-01

前言： 现在在企业中一般都是用SSMM框架来进行开发。

SSMM（springmvc + spring + mybatis+ mysql）

从分层角度来说

- springmvc 控制层

- spring service 层

- mybatis dao层

- mysql 数据库

从我个人而言，需要用springboot来搭建SSMM框架，前提是能先用xml配置的方式搭建起来，这样在用springboot的时候，可以思路清晰一些，下面就开始来搭建，我先搭建一份xml 格式SSMM，在由xml 转向springboot，这样就会发现springboot的配置是怎么来的。

思路

创建maven项目

导入pom.xml

配置web.xml

配置数据库连接，连接池，sessionFactory，事务,扫描注入的配置

创建数据库

写测试用例

测试添加

测试事物

完成基本搭建。

后续可以继续配置springmvc

按照上面的思路现在来开始搭建

（1）.创建一个maven项目

（2）.导入pomx.ml

（3）配置web.xml

- 一般我们在配置web.xml 首先会配置web.xml的头

<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xmlns="http://java.sun.com/xml/ns/j2ee" xmlns:javaee="http://java.sun.com/xml/ns/javaee"
xmlns:web="http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd"
xsi:schemaLocation="http://java.sun.com/xml/ns/j2ee http://java.sun.com/xml/ns/j2ee/web-app_2_4.xsd" id="WebApp_ID" version="2.4">

配置spring监听

<!-- Spring监听 -->
<listener >
<listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
</listener>

扩展下：

一般在这里我们会配置spring监听的spring配置文件路径，默认情况下是/WEB-INF/applicationContext.xml

这里我们可以去看下源码，到底是为什么要这么配置

监听器，发现是继承ContextLoader



继续，我们去查看下ContextLoader 源码



发现这个就是我们平时配置的Context-param，原来是这么来的，看注解发现我们可以去org.springframework.web.context.support.XmlWebApplicationContext#DEFAULT_CONFIG_LOCATION 看下监听器的默认配置

继续查看XmlWebApplicationContext



到这里，明白了吧，原来默认配置在这里哈。

继续配置我们的监听文件路径，一般我习惯不用默认配置，设置如下

<!-- spring监听文件地址 -->
<context-param>
<param-name>contextConfigLocation</param-name>
<param-value>classpath:application-context.xml</param-value>
</context-param>

创建application-context.xml

<?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"
xmlns:tx="http://www.springframework.org/schema/tx" xmlns:jdbc="http://www.springframework.org/schema/jdbc"
xmlns:context="http://www.springframework.org/schema/context"
xsi:schemaLocation=" http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-3.0.xsd http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-3.0.xsd http://www.springframework.org/schema/jdbc http://www.springframework.org/schema/jdbc/spring-jdbc-3.0.xsd http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-3.0.xsd http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop-3.0.xsd">
<import resource="config/*.xml" />
</beans>

创建文件夹 config

（3）在文件夹下配置数据库连接，连接池，sessionFactory，事务,扫描注入的配置

- 扫描

- 创建annotation.xml

<?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"
xmlns:tx="http://www.springframework.org/schema/tx" xmlns:jdbc="http://www.springframework.org/schema/jdbc"
xmlns:context="http://www.springframework.org/schema/context"
xsi:schemaLocation=" http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-3.0.xsd http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-3.0.xsd http://www.springframework.org/schema/jdbc http://www.springframework.org/schema/jdbc/spring-jdbc-3.0.xsd http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-3.0.xsd http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop-3.0.xsd">

<!-- 扫描配置，排除扫描controller -->
<context:component-scan base-package="com.study">
<context:exclude-filter type="annotation" expression="org.springframework.stereotype.Controller"/>
</context:component-scan>
<!-- 隐式地向 Spring容器注册AutowiredAnnotationBeanPostProcessor、
RequiredAnnotationBeanPostProcessor、CommonAnnotationBeanPostProcessor
以及PersistenceAnnotationBeanPostProcessor这4个BeanPostProcessor -->
<context:annotation-config/>

</beans>

数据库连接 - 读取配置文件

创建properties.xml（读取配置文件）

<?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"

xsi:schemaLocation=" http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-3.0.xsd http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-3.0.xsd http://www.springframework.org/schema/jdbc http://www.springframework.org/schema/jdbc/spring-jdbc-3.0.xsd http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-3.0.xsd http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop-3.0.xsd">

<bean class="org.springframework.beans.factory.config.PropertyPlaceholderConfigurer">
<property name="locations">
<list>
<!-- 配置Jdbc -->
<value>classpath:properties/jdbc.properties</value>

</list>

</property>
</bean>
</beans>

jdbc连接

<?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"

<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>

</beans>

mybatis 配置

<?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"
xmlns:tx="http://www.springframework.org/schema/tx" xmlns:jdbc="http://www.springframework.org/schema/jdbc"
xmlns:context="http://www.springframework.org/schema/context"
xsi:schemaLocation=" http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-3.0.xsd http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-3.0.xsd http://www.springframework.org/schema/jdbc http://www.springframework.org/schema/jdbc/spring-jdbc-3.0.xsd http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-3.0.xsd http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop-3.0.xsd">

<bean   class="org.mybatis.spring.SqlSessionFactoryBean">
<property name="dataSource" ref="dataSource" />

<property name="typeAliasesPackage" value="com.study.bean"/>
<!-- <property name="configLocation" value="classpath:mybatis-config.xml"/> -->

</bean>

<!-- 配置Mybatis扫描 -->
<bean class="org.mybatis.spring.mapper.MapperScannerConfigurer">
<property name="basePackage" value="com.study.dao"/>
</bean>

</beans>

创建事务transation.xml

<?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"
xmlns:tx="http://www.springframework.org/schema/tx" xmlns:jdbc="http://www.springframework.org/schema/jdbc"

xsi:schemaLocation=" http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-3.0.xsd http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-3.0.xsd http://www.springframework.org/schema/jdbc http://www.springframework.org/schema/jdbc/spring-jdbc-3.0.xsd http://www.springframework.org/schema/tx http://www.springframework.org/schema/tx/spring-tx-3.0.xsd http://www.springframework.org/schema/aop http://www.springframework.org/schema/aop/spring-aop-3.0.xsd">

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

</beans>

在properties文件中创建jdbc.properties

driverClass=com.mysql.jdbc.Driver
jdbcUrl=jdbc:mysql://localhost:3306/test?characterEncoding=UTF-8
user=root
password=

配置文件到这里就结束了，终于结束了。。

（4）开始创建数据库

创建 test数据库，创建下面的表

CREATE TABLE `test_tb` (
`id` int(11) NOT NULL AUTO_INCREMENT,
`name` varchar(255) DEFAULT NULL,
`birthday` datetime DEFAULT NULL,
PRIMARY KEY (`id`)
) ENGINE=InnoDB AUTO_INCREMENT=1 DEFAULT CHARSET=utf8;

（5）写测试用例

一般我会写一个通用的BaseTest,这样其他测试类直接继承就可以开始测试，不用去理会测试环境的配置

package com.study.test;

import org.junit.runner.RunWith;
import org.springframework.test.context.ContextConfiguration;
import org.springframework.test.context.junit4.SpringJUnit4ClassRunner;

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

}

package com.study.test;

import java.util.Date;

import org.junit.Test;
import org.springframework.beans.factory.annotation.Autowired;

import com.study.bean.TestTb;
import com.study.service.TestTbService;

public class TestTestTb extends BaseTest{
@Autowired
private TestTbService testTbService;

@Test
public void test_add(){
TestTb tb = new TestTb();
tb.setName("test");
tb.setBirthday(new Date());
testTbService.add(tb);
}
}

（6）写model,service,dao,mapper，开始测试

附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.study.dao.TestTbDao">
<!--  添加测试数据  -->
<insert id="addTestTb" parameterType="TestTb">
insert into test_tb
(name,birthday)
values
(#{name},#{birthday})
</insert>
</mapper>

其他代码比较简单，就不附上了

（7）测试事务，一般写测试事务的时候，我会在service层抛出异常，如果异常抛出，数据数据没有添加成功，则事务配置成功，反之则没有成功。
