Spring基于xml的CRUD

1.在pom.xml中引入相应jar包

<dependencies>
    <dependency>
        <groupId>org.springframework</groupId>
        <artifactId>spring-context</artifactId>
        <version>5.0.2.RELEASE</version>
    </dependency>

    <dependency>
        <groupId>commons-dbutils</groupId>
        <artifactId>commons-dbutils</artifactId>
        <version>1.4</version>
    </dependency>

    <dependency>
        <groupId>mysql</groupId>
        <artifactId>mysql-connector-java</artifactId>
        <version>5.1.6</version>
    </dependency>
    <!--连接池-->
    <dependency>
        <groupId>c3p0</groupId>
        <artifactId>c3p0</artifactId>
        <version>0.9.1.2</version>
    </dependency>

    <dependency>
        <groupId>junit</groupId>
        <artifactId>junit</artifactId>
        <version>4.13</version>
        <scope>test</scope>
    </dependency>

    <dependency>
        <groupId>org.springframework</groupId>
        <artifactId>spring-test</artifactId>
        <version>5.0.2.RELEASE</version>
    </dependency>
</dependencies>

2.在resources目录下创建bean.xml配置文件，并注入service、dao中相应类的依赖。

<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
       xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
       xsi:schemaLocation="http://www.springframework.org/schema/beans
        http://www.springframework.org/schema/beans/spring-beans.xsd">

    <!--配置service-->
    <bean id="accountService" class="io.github.lonelyMrZhang.service.impl.AccountServiceImpl">
        <!--注入dao-->
        <property name="accountDao" ref="accountDao"></property>
    </bean>
    <!--配置AccountDao-->
    <bean id="accountDao" class="io.github.lonelyMrZhang.dao.impl.AccountDaoImpl">
        <!--注入QueryRunner-->
        <property name="runner" ref="queryRunner"></property>
    </bean>
    <!--配置QueryRunner-->
    <bean id="queryRunner" class="org.apache.commons.dbutils.QueryRunner" scope="prototype">
        <!--注入数据源-->
        <constructor-arg name="ds" ref="dataSource"></constructor-arg>
    </bean>

    <!--配置数据源-->
    <bean id="dataSource" class="com.mchange.v2.c3p0.ComboPooledDataSource">
        <!--连接数据库的必备信息-->
        <property name="driverClass" value="com.mysql.jdbc.Driver"></property>
        <property name="jdbcUrl" value="jdbc:mysql://192.168.31.254:3306/coupling_code"></property>
        <property name="user" value="root"></property>
        <property name="password" value="2486"></property>
    </bean>
</beans>

注意<property>标签是基于set方法进行注入的，所以在.java文件中必须要有相应的set方法。
