springboot整合成c3p0

一，pom文件

     <dependency>
            <groupId>com.mchange</groupId>
            <artifactId>c3p0</artifactId>
            <version>0.9.5.4</version>
        </dependency>

二，配置文件

c3p0.jdbcUrl=jdbc:mysql://x.x.x.x:xx/xxx?useUnicode=true&characterEncoding=UTF-8&serverTimezone=UTC&&serverTimezone=Asia/Shanghai
c3p0.user=root
c3p0.password=123456
c3p0.driverClass=com.mysql.cj.jdbc.Driver
c3p0.minPoolSize=2
c3p0.maxPoolSize=10
c3p0.maxIdleTime=1800000
c3p0.acquireIncrement=3
c3p0.maxStatements=1000
c3p0.initialPoolSize=3
c3p0.idleConnectionTestPeriod=60
c3p0.acquireRetryAttempts=30
c3p0.acquireRetryDelay=1000
c3p0.breakAfterAcquireFailure=false
c3p0.testConnectionOnCheckout=false

配置类

@Configuration
public class DataSourceConfig {
    @Bean(name = "dataSource")
    @Qualifier(value = "dataSource")
    @Primary
    @ConfigurationProperties(prefix = "c3p0")
    public DataSource dataSource()
    {
        return DataSourceBuilder.create().type(com.mchange.v2.c3p0.ComboPooledDataSource.class).build();
    }
}
