解决Spring报错:Error creating bean with name
在使用springboot构建 oltu-oauth的时候启动项目报错
在网上找一下没找到 ,之前项目对比发现忘记在WebApplication中少加了个注解
加上之后问题解决,查了下这个注解(横线以下是对@MapperSecan的介绍):
之前是，直接在Mapper类上面添加注解@Mapper，这种方式要求每一个mapper类都需要添加此注解，麻烦。
通过使用@MapperScan可以指定要扫描的Mapper类的包的路径，比如：
@SpringBootApplication
@MapperScan("com.lz.water.monitor.mapper")
// 添加对mapper包扫描
public class Application {
public static void main(String[] args) {
SpringApplication.run(Application.class, args); }
}同时，使用@MapperScan注解多个包
@SpringBootApplication
@MapperScan({"com.kfit.demo","com.kfit.user"})
public class App {
public static void main(String[] args) {
SpringApplication.run(App.class, args);
}
} 如果如果mapper类没有在Spring Boot主程序可以扫描的包或者子包下面，可以使用如下方式进行配置
@SpringBootApplication
@MapperScan({"com.kfit.*.mapper","org.kfit.*.mapper"})
public class App {
public static void main(String[] args) {
SpringApplication.run(App.class, args);
}
} 导入seata报错:Error creating bean with name ‘dataSourceProxyConfig‘
先去找配置的 registry.conf和file.conf有没有问题，如果没有问题那么就是你yml中配置了数据源
datasource: driver-class-name: com.mysql.jdbc.Driver url: jdbc:mysql://localhost:3306/gift_auth username: root password: xxx
同时在你这个服务中又配置了数据源 这里可以是mybatis-plus版也可以是mybatis版，导致和yml中配置的数据源冲突了。
package com.wangling.config;
import com.alibaba.druid.pool.DruidDataSource;
import com.baomidou.mybatisplus.spring.MybatisSqlSessionFactoryBean;
import io.seata.rm.datasource.DataSourceProxy;
import org.mybatis.spring.transaction.SpringManagedTransactionFactory;
import org.springframework.beans.factory.annotation.Value;
import org.springframework.boot.context.properties.ConfigurationProperties;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.context.annotation.Primary;
import org.springframework.core.io.support.PathMatchingResourcePatternResolver;
import javax.sql.DataSource;
@Configuration
public class DataSourceConfiguration {
//mapper.xml路径
@Value("${mybatis-plus.mapper-locations}")
private String mapperLocations;
//手动配置bean
@Bean
@ConfigurationProperties("spring.datasource")
public DataSource druidDataSource(){
return new DruidDataSource();
}
@Bean
public MybatisSqlSessionFactoryBean sqlSessionFactoryBean(DataSourceProxy dataSourceProxy) throws Exception {
//处理MybatisPlus
MybatisSqlSessionFactoryBean factory = new MybatisSqlSessionFactoryBean();
factory.setDataSource(dataSourceProxy);
factory.setMapperLocations(new PathMatchingResourcePatternResolver().getResources(mapperLocations));
//事务管理工厂
factory.setTransactionFactory(new SpringManagedTransactionFactory());
return factory;
}
@Bean
public DataSourceProxy dataSource() {
return new DataSourceProxy(druidDataSource());
}
}所以在自定义配置源里面加入@Primary 默认自定义配置先启动
package com.wangling.config;
import com.alibaba.druid.pool.DruidDataSource;
import com.baomidou.mybatisplus.spring.MybatisSqlSessionFactoryBean;
import io.seata.rm.datasource.DataSourceProxy;
import org.mybatis.spring.transaction.SpringManagedTransactionFactory;
import org.springframework.beans.factory.annotation.Value;
import org.springframework.boot.context.properties.ConfigurationProperties;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;
import org.springframework.context.annotation.Primary;
import org.springframework.core.io.support.PathMatchingResourcePatternResolver;
import javax.sql.DataSource;
@Configuration
public class DataSourceConfiguration {
//mapper.xml路径 这里如果是mybatis就把mybatis-plus修改了同时修改yml中的配置
@Value("${mybatis-plus.mapper-locations}")
private String mapperLocations;
//手动配置bean
@Bean
@ConfigurationProperties("spring.datasource")
@Primary
public DataSource druidDataSource(){
return new DruidDataSource();
}
@Bean
public MybatisSqlSessionFactoryBean sqlSessionFactoryBean(DataSourceProxy dataSourceProxy) throws Exception {
//处理MybatisPlus
MybatisSqlSessionFactoryBean factory = new MybatisSqlSessionFactoryBean();
factory.setDataSource(dataSourceProxy);
factory.setMapperLocations(new PathMatchingResourcePatternResolver().getResources(mapperLocations));
//事务管理工厂
factory.setTransactionFactory(new SpringManagedTransactionFactory());
return factory;
}
@Bean
public DataSourceProxy dataSource() {
return new DataSourceProxy(druidDataSource());
}
}总结
以上为个人经验，希望能给大家一个参考，也希望大家多多支持脚本之家。
