springboot注入默认使用className作为注入的key，如果两个className一样，无法注入
添加配置CoreConfiguration
package com.statcore;
import com.xmeport.statcore.util.AnnotationBeanNameGenerator;
import org.mybatis.spring.annotation.MapperScan;
import org.springframework.context.annotation.ComponentScan;
import org.springframework.context.annotation.Configuration;
@Configuration
@ComponentScan(nameGenerator = AnnotationBeanNameGenerator.class)
@MapperScan(value = "com.xmeport.statcore.mapper" ,nameGenerator = AnnotationBeanNameGenerator.class)
public class CoreConfiguration {
}
创建AnnotationBeanNameGenerator类
