开发Restful服务

创建服务实现类

创建一个class，添加下列注解和代码，配置接口访问的入口，需要注意的是Path中的路径必须是与web.xml中resteasyservlet配置的相同，否则将无法访问到接口，此处我们配置在/rest/services下

创建配置文件

在编辑的java同目录下创建文件restconfig.properties并录入以下内容（等号后是对应的类全名）

resteasy.resources=com.xcmg.service.ProcessStartService

编辑web.xml文件

编辑web.xml文件，在rest.config.locations下的param-value标签下新增restconfig.properties对应路径，需要增加英文逗号与已有内容分开，保存编辑后需要右键web.xml文件进行部署。

注意事项：

1.修改了web.xml要手动部署web.xml
2.web.xml中的servlet-mapping下的url-pattern要和配置访问的地址对应
3.在rest.config.locations下的param-value标签下新增restconfig.properties对应路径
