jsp页面获取所有用户信息代码如下:
<%@page contentType="text/html" pageEncoding="UTF-8"%>
<%@page import="java.util.*"%>
<%@page import="com.liferay.portal.service.UserLocalServiceUtil"%>
<%@page import="com.liferay.portal.model.User"%>
<%@page import="cn.gov.jssw.webcms.dao.*"%>
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN"
"http://www.w3.org/TR/html4/loose.dtd">
<%
List<User> users = (List<User>)session.getAttribute("users");
if(users==null) users = UserLocalServiceUtil.getUsers(0, 20);
PageSet pageset=(PageSet)request.getAttribute("pageSet");
if(pageset==null){
int rowcount=UserLocalServiceUtil.getUsersCount();
pageset=new PageSet();
pageset.setRowcount(rowcount);
pageset.setCurrentpage(1);
pageset.setPagecount((rowcount+20-1)/20);
pageset.setPagesize(20);
request.setAttribute("pageSet", pageset);
}
%>
其中UserLocalServiceUtil 类引用的是portal-service.jar ,但是现在运行此页面的时候出现下面的错误:
7: "http://www.w3.org/TR/html4/loose.dtd">
8: <%
9: List<User> users = (List<User>)session.getAttribute("users");
10: if(users==null) users = UserLocalServiceUtil.getUsers(0, 20);
11: PageSet pageset=(PageSet)request.getAttribute("pageSet");
12: if(pageset==null){
13: int rowcount=UserLocalServiceUtil.getUsersCount();

我查看了下UserLocalServiceUtil 类的源码，报错原因是UserLocalServiceUtil类里面调用的接口为空，才报出上面的错误java.lang.RuntimeException: UserLocalService is not set UserLocalServiceUtil类相应源码如下:
public static UserLocalService getService() {
if (_service == null) {
throw new RuntimeException("UserLocalService is not set");
}
return _service;
}
public void setService(UserLocalService service) {
_service = service;
}
private static UserLocalService _service;

你用的liferay是哪个版本的啊？
我用的4.3.3，都没有这个方法，不过我用的下面的方法能够正确执行UserLocalServiceUtil.getUserByScreenName(1,userName) 你这个应该是没有通过spring取得UserLocalServiceUtil的实例，因此没有注入相应的UserLocalService实例。 |
