Java开发调用GP自定义工具报错AutomationException: 0x5 - Access is denied. in 'Invoke'

java中调用的包为ArcObject10.3.1，在实例化GeoProcessor那一步就直接报错了代码如下：
@PostMapping(value = "test") public ReturnData test(HttpServletRequest request, HttpServletResponse response) throws IOException{ 
try { 
    GeoProcessor gp = new GeoProcessor(); 
    gp.addToolbox("C:\\Users\\Administrator\\Documents\\ArcGIS\\DZ_GP.tbx"); 
    IVariantArray parameters = new VarArray(); 
    parameters.add("C:\\Users\\Administrator\\Desktop\\test\\riskWarn\\0524r"); 
 parameters.add("C:\\Users\\Administrator\\Desktop\\test\\riskWarn\\0524testjava\\fxyjt.shp"); 
    gp.execute("风险预警图处理",parameters,null); 
}catch (Exception e){ 
    LOGGER.info("测试错误"+e); 
} 
return new ReturnData(); 
}
