Spring普通类方法或通过反射调用的方法访问Mapper层方法失败问题解决办法

解决方法

• 在类上添加@Component注解
• 使用注解@PostConstruct编写初始化方法,在类初始化的时候把mapper注入进来

示例代码

import com.common.mapper.EqcMapper;
import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Component;
import javax.annotation.PostConstruct;

@Component
public class ServiceImpl {

    @Autowired
    private EqcMapper eqcMapper;

    private static ServiceImpl serviceImplMapper;

    @PostConstruct
    public void init(){
        serviceImplMapper = this;
        serviceImplMapper.eqcMapper = this.eqcMapper;
    }

    public void getName(){
        String name = serviceImplMapper.eqcMapper.getName();
    }
}
