sca的web app,
今天遇到一个特别XX的问题?
先把配置文件列出
一:InformationService.composite文件
<?xml version="1.0" encoding="UTF-8"?>
<composite xmlns="http://www.osoa.org/xmlns/sca/1.0"
targetNamespace="http://sca.spsoft.com.cn"
xmlns:sample="http://sca.spsoft.com.cn"
name="informationService">
<component name="informationServiceComponent">
<implementation.java class="cn.com.spsoft.sca.business.impl.InformationServiceImpl"/>
<reference name="bpService" target="bpServiceComponent"></reference>
<reference name="riService" target="riServiceComponent"></reference>
<reference name="jobService" target="jobServiceComponent"></reference>
</component>
<component name="bpServiceComponent">
<implementation.java class="cn.com.spsoft.sca.business.impl.BasicPayServiceImpl"/>
</component>
<component name="riServiceComponent">
<implementation.java class="cn.com.spsoft.sca.business.impl.RegisterInfoServiceImpl"/>
</component>
<component name="jobServiceComponent">
<implementation.java class="cn.com.spsoft.sca.business.impl.JobFinishServiceImpl"/>
</component>
</composite>
二:下面是测试主方法
public static void main(String args[]) {
SCADomain scaDomain = SCADomain
.newInstance("InformationService.composite");
System.out.println("ComponentNames:"+ scaDomain.getComponentManager().getComponentNames());
InformationService informationService = scaDomain.getService(
InformationService.class, "informationServiceComponent");
}
三:说明
运行该主方法后,出现如下面的异常
ComponentNames:[bpServiceComponent, riServiceComponent, jobServiceComponent, informationServiceComponent]
Exception in thread "main" java.lang.NoSuchMethodError: org.osoa.sca.ServiceReference.getService()Ljava/lang/Object;
at org.apache.tuscany.sca.host.embedded.impl.DefaultSCADomain.getService(DefaultSCADomain.java:365)
at cn.com.spsoft.sca.business.ClientTest.main(ClientTest.java:11)
从上面加载配置文件一步应该是正确的,而且取得了配置的几个构件
但总提示找不到getService方法????
四:主要接口与实现
public interface InformationService {
// 每个人基础工资查询（BasicPayService）
public double findByuid(String uid);
// 查询个人注册信息(RegisterInfoService)
public String findInfoByuid(String uid);
// 查询工作完成情况(JobFinishService)
public double findJob(String uid);
}
在该接口的实现中进行了注入
public class InformationServiceImpl implements InformationService {
private BasicPayService bpService;
private RegisterInfoService riService;
private JobFinishService jobService;
@Reference
public void setBpService(BasicPayService bpService) {
this.bpService = bpService;
}
@Reference
public void setRiService(RegisterInfoService riService) {
this.riService = riService;
}
@Reference
public void setJobService(JobFinishService jobService) {
this.jobService = jobService;
}
public double findByuid(String uid) {
// TODO Auto-generated method stub
return bpService.findByuid(uid);
}
public String findInfoByuid(String uid) {
// TODO Auto-generated method stub
return riService.findInfoByuid(uid);
}
public double findJob(String uid) {
// TODO Auto-generated method stub
return jobService.findJob(uid);
}
}
找不到原因,急中...
五:在jsp访问方式中是正确的
如index.jsp
<%@ page language="java" import="java.util.*" pageEncoding="GBK"%>
<!-- 导入内容 -->
<%@ page import="org.osoa.sca.CompositeContext"%>
<%@ page import="org.osoa.sca.CurrentCompositeContext"%>
<%@ page import="cn.com.spsoft.sca.business.MSG"%>
<%@ page import="cn.com.spsoft.sca.business.InformationService" %>
<!-- 代码段 -->
<%
//取得构件上下文环境
CompositeContext context = CurrentCompositeContext.getContext();
//加载接口MSG对应的服务,参数为接口，组件名称
MSG msg = context.locateService(MSG.class, "msgComponent");
InformationService informationService = context.locateService(
InformationService.class, "informationServiceComponent");
%>
<%
String path = request.getContextPath();
String basePath = request.getScheme() + "://"
+ request.getServerName() + ":" + request.getServerPort()
+ path + "/";
%>
