使用@PostConstruct 初始化加载静态对象

@Component
public class APIServerUtil {

    public static APIServerUtil apiServerUtil;  // 初始化

    @Autowired
    private MHbpzMapper mHbpzMapper;

    @PostConstruct  //初始化
    public void init() {
        apiServerUtil = this;
        apiServerUtil.mHbpzMapper = this.mHbpzMapper;
    }

    /***
     * 获取查询接口地址
     * @return
     */
    public String queryAPIAddress(){
        LambdaQueryWrapper<MHbpz> Wrapper =  new LambdaQueryWrapper<>();
        Wrapper.eq(MHbpz::getType,CustomData.QUERY_API_ADDRESS);
        MHbpz mHbpz = mHbpzMapper.selectOne(Wrapper);
        String queryAPIAddress = "http://"+mHbpz.getIp()+":"+mHbpz.getPort()+mHbpz.getUrl();
        return queryAPIAddress;
    }
}
