springboot整合druid连接池

Spring Boot整合Druid连接池的步骤如下：

1. 在pom.xml文件中添加Druid和JDBC依赖：

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

<dependency>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-starter-jdbc</artifactId>
</dependency>

2. 在application.properties文件中配置Druid连接池：

spring.datasource.url=jdbc:mysql://localhost:3306/test
spring.datasource.username=root
spring.datasource.password=root
spring.datasource.driver-class-name=com.mysql.jdbc.Driver

# Druid配置
spring.datasource.type=com.alibaba.druid.pool.DruidDataSource
spring.datasource.druid.initial-size=5
spring.datasource.druid.min-idle=5
spring.datasource.druid.max-active=20
spring.datasource.druid.test-on-borrow=true
spring.datasource.druid.test-on-return=false
spring.datasource.druid.test-while-idle=true
spring.datasource.druid.time-between-eviction-runs-millis=60000
spring.datasource.druid.min-evictable-idle-time-millis=300000
spring.datasource.druid.validation-query=SELECT 1 FROM DUAL
spring.datasource.druid.filters=stat,wall,log4j
spring.datasource.druid.connection-properties=druid.stat.mergeSql=true;druid.stat.slowSqlMillis=500

3. 在启动类上添加注解@EnableTransactionManagement和@Bean注解创建DruidDataSource：

@SpringBootApplication
@EnableTransactionManagement
public class Application {

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

    @Bean
    @ConfigurationProperties(prefix = "spring.datasource.druid")
    public DataSource druidDataSource() {
        return new DruidDataSource();
    }
}

4. 在需要使用数据库的地方注入JdbcTemplate：

@Autowired
private JdbcTemplate jdbcTemplate;

以上就是Spring Boot整合Druid连接池的步骤。
