在加拿大
请问it前辈，有没有人帮我看看这个command button action怎么总是不起作用啊? 搞了一下午了，就是不行！ primefaces + hibernate + spring + maven的项目，我在mysql workbench里面看不到更新employee条目，而且这个action根本没有调用empBean的addEmployee方法。 prime faces 用户手册也看了，无解。跪谢！！代码:<!DOCTYPE html><html xmlns="http://www.w3.org/1999/xhtml" xmlns:f="http://java.sun.com/jsf/core" xmlns:h="http://java.sun.com/jsf/html" xmlns:ui="http://java.sun.com/jsf/facelets" xmlns:p="http://primefaces.org/ui"> <h:head> <title>My Team</title> </h:head> <h:body> <h2>My Team</h2> <hr/> <h:outputText value="Hello JSF"/> <p:editor value="Hello Primefaces"/> <h:form id="empForm"> <p:commandButton value="Add default" action="#{empBean.addEmployee}" update="empForm"/> <h3>Hello</h3> <h:outputText id="employeeId" value="#{empBean.employee.firstName} #{empBean.employee.lastName}"/> </h:form> </h:body></html>代码:package managedBeans;import java.io.Serializable;import javax.faces.bean.SessionScoped;import org.springframework.beans.factory.annotation.Autowired;import org.springframework.stereotype.Component;import model.Employee;import services.EmployeeService;@Component("empBean")@SessionScopedpublic class EmployeeBean implements Serializable{ private static final long serialVersionUID = 1L; private Employee employee = new Employee(); @Autowired private EmployeeService empService; private Employee emp1; private Employee emp2; public EmployeeBean(){ emp1 = new Employee(); emp1.setFirstName("Huong"); emp1.setLastName("Nguyen"); emp2 = new Employee(); emp2.setFirstName("Khang"); emp2.setLastName("Le");} public void addEmployee(){ empService.addEmployee(emp1); empService.addEmployee(emp2); employee= empService.findEmployeeById(emp1.getEmpId()); System.out.println("bean addEmployee called!!"); } public Employee getEmployee() { return employee; } public void setEmployee(Employee employee) { this.employee = employee; }}
