1.登录官网申请Id和密码
2.下载 java sdk
登录如下链接参考官方文档部署
https://docs.geetest.com/install/deploy/server/java
3.本文对官方java文档稍作修改添加如下几行，用于设置自己的id和key.请根据实际情况填写
public static final String id = "你的id"; public static final String key = "你的key"; public static final boolean newfailback = true;
4.修改后结果如下：

5.把该段段代码放入工具包中
6.编写controller,接受页面请求
package com.huawei.manager.controller; import java.util.HashMap; import javax.servlet.http.HttpServletRequest; import com.huawei.common.utils.GeetestLib; import org.springframework.stereotype.Controller; import org.springframework.web.bind.annotation.RequestMapping; import org.springframework.web.bind.annotation.RequestMethod; import org.springframework.web.bind.annotation.ResponseBody; /** * This is Description * * @author 王明飞 * @date 2018/08/30 */ @Controller public class UserController { @RequestMapping(value = "/geetestInit",method = RequestMethod.GET) @ResponseBody public String geetesrInit(HttpServletRequest request){ GeetestLib gtSdk = new GeetestLib(GeetestLib.id, GeetestLib.key,GeetestLib.newfailback); String resStr = "{}"; //自定义参数,可选择添加 HashMap<String, String> param = new HashMap<String, String>(); //进行验证预处理 int gtServerStatus = gtSdk.preProcess(param); //将服务器状态设置到session中 request.getSession().setAttribute(gtSdk.gtServerStatusSessionKey, gtServerStatus); resStr = gtSdk.getResponseStr(); return resStr; } }
运行项目即可
