springboot+druid配置无效

使用druid-spring-boot-starter 提供的配置方法，运行之后应用不到druid连接处，而是默认的HikariPool

运行的类


package com.druid;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;

@SpringBootApplication(scanBasePackages="com.alibaba.druid.spring.boot")
public class DruidApplication {

    public static void main(String[] args) {
        SpringApplication.run(DruidApplication.class, args);
    }
}

参考 配置进行详细的对比：https://blog.csdn.net/u010513756/article/details/80235876

问题我自己已经解决了，是druid版本问题 ，如果用的druid-spring-boot-starter版本为1.1.10 ，那么搭配的druid版本要是1.1.9，其他版本我不知道，但用1.1.10的druid就肯定会出现我上面说的问题，；
现在网上搜索springboot +druid 都是要我们写一堆代码，其实大家可以用druid-spring-boot-starter去做，不用写一句代码，只要配置下就可以了，而且还支持多数据库配置，参考https://github.com/alibaba/druid/tree/master/druid-spring-boot-starter
最后附上pom.xml中druid的配置,

 <dependency>
            <groupId>com.alibaba</groupId>
            <artifactId>druid</artifactId>
            <version>1.1.9</version>
        </dependency>
        <dependency>
            <groupId>com.alibaba</groupId>
            <artifactId>druid-spring-boot-starter</artifactId>
            <version>1.1.10</version>
        </dependency>

控制台一直都打印是：

 Located MBean 'dataSource': registering with JMX server as MBean [com.zaxxer.hikari:name=dataSource,type=HikariDataSource]

application:

# 只有下面三个是必填项（使用内嵌数据库的话这三个也可以不用填，会使用默认配置），其他配置不是必须的
spring.datasource.url=jdbc:h2:file:./demo-db
spring.datasource.username=sa
spring.datasource.password=sa
# driver-class-name 非必填可根据url推断
spring.datasource.driver-class-name=org.h2.Driver

#Druid 数据源配置，继承spring.datasource.* 配置，相同则覆盖
spring.datasource.druid.initial-size=2
spring.datasource.druid.max-active=30
spring.datasource.druid.min-idle=2
spring.datasource.druid.max-wait=1234
spring.datasource.druid.pool-prepared-statements=true
spring.datasource.druid.max-pool-prepared-statement-per-connection-size=5
#spring.datasource.druid.max-open-prepared-statements= #等价于上面的max-pool-prepared-statement-per-connection-size
spring.datasource.druid.validation-query=select 1
spring.datasource.druid.validation-query-timeout=1

spring.datasource.druid.test-on-return=true
spring.datasource.druid.test-while-idle=true
spring.datasource.druid.time-between-eviction-runs-millis=10000
spring.datasource.druid.min-evictable-idle-time-millis=30001
spring.datasource.druid.async-close-connection-enable=true


spring.datasource.druid.aop-patterns=com.alibaba.druid.spring.boot.demo.service.*

# 自定义StatFilter 配置 其他 Filter 不再演示
spring.datasource.druid.filter.stat.db-type=h2
spring.datasource.druid.filter.stat.log-slow-sql=true
spring.datasource.druid.filter.stat.slow-sql-millis=2000

# JPA
spring.jpa.show-sql= true
spring.jpa.hibernate.ddl-auto=create-drop

spring.datasource.type=com.alibaba.druid.pool.DruidDataSource, 加上这一句试试。

　添加hibernate依赖，mysql驱动，druid依赖。这里hibernate，mysql并不需要选择版本，添加parent依赖自动为你寻找对应的版本。

　　由于springboot强调去XML配置文件，强化注解。druid注入时，使用注解。

复制代码
package hello.configuration;

import javax.sql.DataSource;

import org.springframework.boot.bind.RelaxedPropertyResolver;
import org.springframework.context.EnvironmentAware;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.core.env.Environment;
import org.springframework.transaction.annotation.EnableTransactionManagement;

import com.alibaba.druid.pool.DruidDataSource;

@Configuration
@EnableTransactionManagement
public class DataBaseConfiguration implements EnvironmentAware {

private RelaxedPropertyResolver propertyResolver;

@Override
public void setEnvironment(Environment env) {
    this.propertyResolver = new RelaxedPropertyResolver(env, "spring.datasource.");
}

@Bean(destroyMethod = "close", initMethod = "init")
public DataSource writeDataSource() {
    System.out.println("注入druid！！！");

    DruidDataSource datasource = new DruidDataSource();
    datasource.setUrl(propertyResolver.getProperty("url"));
    datasource.setDriverClassName(propertyResolver.getProperty("driver-class-name"));
    datasource.setUsername(propertyResolver.getProperty("username"));
    datasource.setPassword(propertyResolver.getProperty("password"));
    datasource.setInitialSize(Integer.valueOf(propertyResolver.getProperty("initialSize")));
    datasource.setMinIdle(Integer.valueOf(propertyResolver.getProperty("minIdle")));
    datasource.setMaxWait(Long.valueOf(propertyResolver.getProperty("maxWait")));
    datasource.setMaxActive(Integer.valueOf(propertyResolver.getProperty("maxActive")));
    datasource.setMinEvictableIdleTimeMillis(Long.valueOf(propertyResolver.getProperty("minEvictableIdleTimeMillis")));
    return datasource;
}

}

　　application.properties配置文件，springboot推荐使用YAML格式作为资源配置文件首选，博主懒，一直用properties文件。项目启动时，会自动读取。

　　驱动类Application.java

复制代码
package hello;

import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.context.annotation.Bean;
import org.springframework.orm.jpa.vendor.HibernateJpaSessionFactoryBean;

@SpringBootApplication
public class Application {
public static void main(String[] args) {
SpringApplication.run(Application.class, args);
}

/**
 * 注入sessionfatory
 * @return
 */
@Bean
public HibernateJpaSessionFactoryBean sessionFactory() {
    return new HibernateJpaSessionFactoryBean();
}

}

复制代码

　　此时sessionfactory注入成功。

在springboot配置文件下制定配置文件
用下面制定使用druid连接池
spring.datasource.type=com.alibaba.druid.pool.DruidDataSource
再次启动尝试
