原因:

VrPanoramaServiceImpl类中注入了IVrBusinessHallService类,

VrBusinessHallServiceImpl中注入了IVrPanoramaService类.

产生了循环依赖的问题

解决:

使用setter方法

如:

@Autowired
private IVrPointService vrPointService;

private IVrBusinessHallService businessHallService;

//todo 使用setter解决循环依赖问题
@Autowired
public void setBusinessHallService(IVrBusinessHallService businessHallService){
    this.businessHallService = businessHallService;
}

同时,另一个类中

private IVrPanoramaService panoramaService;

@Autowired
public void setPanoramaService(IVrPanoramaService panoramaService){
    this.panoramaService = panoramaService;
}
