groovy编写webservice服务端和客户端(含连接数据并输出JSON数据)
个人总结，网上几乎没有此方面资料，有一篇帖子，按照其内容无法运行。
注意：请以帖子内容为准，附件为参考
环境：windows7+jdk1.6.0.31+groovy1.8.6
1. 安装jdk和groovy并配置环境变量，略。
2. 安装groovyws0.5.2
3. 编写服务（这里写2个例子，一个是算术、一个是格式化日期）：
1）算术服务
2）格式化日期服务
3. 编写服务启动groovy脚本
4. 编写客户端测试groovy脚本
============= 华丽的分割线 =================
补充：编写连接数据库的服务并返回JSON格式数据
DataService.groovy
并添加到服务启动的groovy脚本中：
调用方法1：
输出结果：
调用方法2：
输出结果：
调用方法3：

环境：windows7+jdk1.6.0.31+groovy1.8.6
1. 安装jdk和groovy并配置环境变量，略。
2. 安装groovyws0.5.2
命令行>：grape install org.codehaus.groovy.modules groovyws 0.5.2
3. 编写服务（这里写2个例子，一个是算术、一个是格式化日期）：
1）算术服务
class MathService {
double add(double arg0, double arg1) {
return (arg0 + arg1)
}
double square(double arg0) {
return (arg0 * arg0)
}
}
2）格式化日期服务
class DateFormatService{
String format(long time){
new Date(time).format('yyyy年MM月dd日')
}
}
3. 编写服务启动groovy脚本
import groovyx.net.ws.WSServer
@Grab(group='org.codehaus.groovy.modules', module='groovyws', version='0.5.2')
def server = new WSServer()
server.setNode("DateFormatService", "http://10.14.3.149:6980/DateFormatService")
server.start()
def s1 = new WSServer()
s1.setNode("MathService", "http://10.14.3.149:6980/MathService")
s1.start()
4. 编写客户端测试groovy脚本
import groovyx.net.ws.WSClient
@Grab(group='org.codehaus.groovy.modules', module='groovyws', version='0.5.2')
def printDate(){
def proxy = new WSClient("http://10.14.3.149:6980/DateFormatService?wsdl", this.class.classLoader)
proxy.initialize()
println "今天是${proxy.format(new Date().time)}"
}
printDate()
============= 华丽的分割线 =================
补充：编写连接数据库的服务并返回JSON格式数据
DataService.groovy
import groovy.sql.Sql
import groovy.json.JsonOutput
class DataService{
String poses(){
def db = Sql.newInstance("jdbc:oracle:thin:@(DESCRIPTION =(ADDRESS_LIST = (ADDRESS = (PROTOCOL = TCP)(HOST = 10.14.3.148)(PORT = 1521)))(CONNECT_DATA =(SID = orcl)))","ecard","ecard","oracle.jdbc.driver.OracleDriver")
def poses = db.rows("select * from OCS_DM_Terminal ")
def retJson = new JsonOutput()
return retJson.toJson(poses)
}
}
并添加到服务启动的groovy脚本中：
import groovyx.net.ws.WSServer
@Grab(group='org.codehaus.groovy.modules', module='groovyws', version='0.5.2')
def server = new WSServer()
server.setNode("DateFormatService", "http://10.14.131.114:6980/DateFormatService")
server.start()
def s1 = new WSServer()
s1.setNode("MathService", "http://10.14.131.114:6980/MathService")
s1.start()
def s2 = new WSServer()
s2.setNode("DataService", "http://10.14.131.114:6980/DataService")
s2.start()
调用方法1：
import groovyx.net.ws.WSClient
@Grab(group='org.codehaus.groovy.modules', module='groovyws', version='0.5.2')
def test(){
def url = "http://10.14.131.114:6980/DataService?WSDL"
def proxy = new WSClient(url, this.class.classLoader)
proxy.initialize()
def ret = proxy.poses()
println ret.toString()
}
test()
输出结果：

import groovyx.net.ws.WSClient
import groovy.json.JsonSlurper
@Grab(group='org.codehaus.groovy.modules', module='groovyws', version='0.5.2')
def test(){
def url = "http://10.14.131.114:6980/DataService?WSDL"
def proxy = new WSClient(url, this.class.classLoader)
proxy.initialize()
def ret = proxy.poses()
def slurper = new JsonSlurper()
def states = slurper.parseText(ret)
states.each{
println it.NAME
}
// println ret
}
test()
