spring讀取properties配置

@Component
public class BaseConfigPath {
private static final String configPath = System.getProperty("user.home")+"/code/config";
public String getConfigPath() {
return configPath;
}
}

根據配置文件路徑解析properties

<context:property-placeholder location="file:#{baseConfigPath.configPath}/jdbc.properties"/>

獲取properties的屬性值
<bean id="dataSource" class="com.mchange.v2.c3p0.ComboPooledDataSource">
<!-- 配置鏈接池屬性 -->
<property name="driverClass" value="${jdbc.driverClassName}"></property>
<property name="jdbcUrl" value="${jdbc.url}"></property>
<property name="user" value="${jdbc.username}"></property>
<property name="password" value="${jdbc.password}"></property>

<!-- c3p0鏈接池的私有屬性 -->
    <property name="maxPoolSize" value="30"></property>
    <property name="minPoolSize" value="10"></property>
    <!-- 關閉鏈接後不自動commit -->
    <property name="autoCommitOnClose" value="false"></property>
    <!-- 獲取鏈接超時時間 -->
    <property name="checkoutTimeout" value="1000"></property>
    <!-- 當獲取鏈接失敗重試次數 -->
    <property name="acquireRetryAttempts" value="2"></property>
</bean>
