发现Druid问题
最近做项目，遇到大量插入的地方，经过大量的调试，最终发现是Druid连接池的问题，（以前一个大项目就遇到过Druid的坑），果断换成c3p0之后，压力测试哗哗上去了。
下面是更换c3p0方法。
1.修改pom.xml
导入c3p0依赖：
<dependency> <groupId>com.mchange</groupId> <artifactId>c3p0</artifactId> <version>0.9.5.5</version> </dependency>
2.修改application.yml
spring: application: name: nh-tst http: encoding: charset: UTF-8 enabled: true force: true datasource: driver-class-name: oracle.jdbc.driver.OracleDriver jpa: hibernate: ddl-auto: none show-sql: true c3p0: jdbcUrl: jdbc:oracle:thin:@xxxxx:1522/prodpdb1 user: xxxxxx password: xxxxxx driverClass: oracle.jdbc.driver.OracleDriver minPoolSize: 3 maxPoolSize: 30 maxIdleTime: 1800000 acquireIncrement: 120 maxStatements: 100000 initialPoolSize: 5 idleConnectionTestPeriod: 60 acquireRetryAttempts: 30 acquireRetryDelay: 10000 breakAfterAcquireFailure: false testConnectionOnCheckout: false
3.增加DataSourceConfiguration.java类
package com.nh.fk.tst.config;
import javax.sql.DataSource;
import org.springframework.beans.factory.annotation.Qualifier;
import org.springframework.boot.context.properties.ConfigurationProperties;
import org.springframework.boot.jdbc.DataSourceBuilder;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.context.annotation.Primary;
import com.mchange.v2.c3p0.ComboPooledDataSource;
@Configuration
public class DataSourceConfiguration {
// c3p0 连接池
@Bean(name = "dataSource")
@Qualifier(value = "dataSource")
@Primary
@ConfigurationProperties(prefix = "c3p0")
public DataSource dataSource() {
return DataSourceBuilder.create().type(ComboPooledDataSource.class).build();
}
}
打包，执行：世界又恢复了和平！！
