3.Pageを編集

@RequestScope
@Page("employee")
public class EmployeePage {
    private EmployeeService employeeService;
    ・・・
    @GET
    @ActionPath("list")
    public Navigation list(WebContext context) {
        List<Employee> employees = employeeService.findAll();
        context.getRequest().setAttribute("employees", employees);
        return Forward.to("/WEB-INF/pages/list.html");
    }
   ・・・
    @Inject
    public void setEmployeeService(EmployeeService employeeService) {
        this.employeeService = employeeService;
    }
}

4.html,mayaaを編集
