报错原因就是因为在DataSourceConfig中使用了
1 @Configuration 2 public class DataSourceConfig { 3 4 @Bean(name = "primaryDataSource") 5 @Qualifier("primaryDataSource") 6 @Primary 7 @ConfigurationProperties(prefix = "spring.datasource.primary") 8 public DataSource primaryDatasource() { 9 return DataSourceBuilder.create().type(com.alibaba.druid.pool.DruidDataSource.class).build(); 10 } 11 12 @Bean(name = "secondaryDataSource") 13 @Qualifier("secondaryDataSource") 14 @ConfigurationProperties(prefix = "spring.datasource.secondary") 15 public DataSource secondaryDataSource() { 16 return DataSourceBuilder.create().type(com.alibaba.druid.pool.DruidDataSource.class).build(); 17 } 18 }
而在application.yml配置文件中使用了jdbc-url从而产生了错误
spring: datasource: type: com.alibaba.druid.pool.DruidDataSource primary: driver-class-name: com.mysql.cj.jdbc.Driver #jdbc-url: jdbc:mysql://localhost/test1?useUnicode=true&characterEncoding=UTF-8&serverTimezone=UTC&useSSL=false url: jdbc:mysql://localhost/test1?useUnicode=true&characterEncoding=UTF-8&serverTimezone=UTC&useSSL=false username: root password: 123456 # 下面为连接池的补充设置，应用到上面所有数据源中 # 初始化大小，最小，最大 name: primary initialSize: 5 minIdle: 5 maxActive: 20 # 配置获取连接等待超时的时间 maxWait: 60000 # 配置间隔多久才进行一次检测，检测需要关闭的空闲连接，单位是毫秒 timeBetweenEvictionRunsMillis: 60000 # 配置一个连接在池中最小生存的时间，单位是毫秒 minEvictableIdleTimeMillis: 300000 validationQuery: SELECT 1 testWhileIdle: true testOnBorrow: false testOnReturn: false # 打开PSCache，并且指定每个连接上PSCache的大小 poolPreparedStatements: true maxPoolPreparedStatementPerConnectionSize: 20 # 配置监控统计拦截的filters，去掉后监控界面sql无法统计，'wall'用于防火墙 filters: stat,wall,log4j # 通过connectProperties属性来打开mergeSql功能；慢SQL记录 connectionProperties: druid.stat.mergeSql=true;druid.stat.slowSqlMillis=5000 logSlowSql: true # 合并多个DruidDataSource的监控数据 useGlobalDataSourceStat: true secondary: driver-class-name: com.mysql.cj.jdbc.Driver #jdbc-url: jdbc:mysql://localhost/test2?useUnicode=true&characterEncoding=UTF-8&serverTimezone=UTC&useSSL=false url: jdbc:mysql://localhost/test2?useUnicode=true&characterEncoding=UTF-8&serverTimezone=UTC&useSSL=false username: root password: 123456 # 下面为连接池的补充设置，应用到上面所有数据源中 # 初始化大小，最小，最大 name: secondary initialSize: 5 minIdle: 5 maxActive: 20 # 配置获取连接等待超时的时间 maxWait: 60000 # 配置间隔多久才进行一次检测，检测需要关闭的空闲连接，单位是毫秒 timeBetweenEvictionRunsMillis: 60000 # 配置一个连接在池中最小生存的时间，单位是毫秒 minEvictableIdleTimeMillis: 300000 validationQuery: SELECT 1 testWhileIdle: true testOnBorrow: false testOnReturn: false # 打开PSCache，并且指定每个连接上PSCache的大小 poolPreparedStatements: true maxPoolPreparedStatementPerConnectionSize: 20 # 配置监控统计拦截的filters，去掉后监控界面sql无法统计，'wall'用于防火墙 filters: stat,wall,log4j # 通过connectProperties属性来打开mergeSql功能；慢SQL记录 connectionProperties: druid.stat.mergeSql=true;druid.stat.slowSqlMillis=5000 logSlowSql: true # 合并多个DruidDataSource的监控数据 useGlobalDataSourceStat: true
解决方法:
将application.yml 配置文件中的jdbc-url改成url就行了
