Java 对接Jenkins API操作（不需要勾选允许站点跨域访问）

最先的是jenkins的跨域问题 如果是一般学习直接关闭  在公司Java对接jenkins的话 还是不关闭

 

 需要的maven 依赖

			com.offbytwo.jenkins
			jenkins-client
			0.3.8
		

JenkinsUtil 不用勾选跨域也可以访问

public class JenkinsUtils {

为什么Java对接jenkins 不需要勾选跨域访问也可以：

job.build(params,true);

 这个方法是带参数构建job true表示需要跨域访问  所以在代码底层为true时 会去 

http://JENKINS_URL/crumbIssuer/api/xml

 获取crumb 然后放进header里面 就可以了
