与blazeds Flex mySQL db连接

Question

我目前正在编写一个小程序，并希望将Blazeds与Flex结合使用。 Blazeds和我的MySQL数据库之间的连接工作正常，但是当我尝试通过运行Catalina服务器上的RemoteObject进行连接时，我总是收到一条错误消息：

[RPC Fault faultString =“没有ID'employeeService'注册任何服务“。 faultCode =“Server.Processing”faultDetail =“null”] at mx.rpc :: AbstractInvoker/http：//www.adobe.com/2006/flex/mx/internal :: faultHandler（）[E：\ dev \ 3.0.x \ frameworks \ projects \ rpc \ src \ mx \ rpc \ AbstractInvoker.as：216] at mx.rpc :: Responder/fault（）[E：\ dev \ 3.0.x \ frameworks \ projects \ rpc \ src \ mx \ rpc \ Responder.as：49] at mx.rpc :: AsyncRequest/fault（）[E：\ dev \ 3.0.x \ frameworks \ projects \ rpc \ src \ mx \ rpc \ AsyncRequest.as： 103] at NetConnectionMessageResponder/statusHandler（）在mx.messaging :: MessageResponder/status（[E：\ dev \ 3.0.x \ frameworks \ projects \ rpc \ src \ mx \ messaging \ channels \ NetConnectionChannel.as：523] ）[E：\ dev \ 3.0.x \ frameworks \ projects \ rpc \ src \ mx \ messaging \ MessageResponder.as：222]

我检查了remoting-config文件和dest ination id在那里。是否需要配置catalina？

Answer 1

只是几件事我能想到的...

• 确保您的Flex项目设置正确引用您的服务器。项目 - >属性 - > Flex服务器。
• 在配置服务器方面，您是否将flex-messaging和blazeds jar添加到您的项目或服务器库中？
• 尽管听起来很愚蠢，但它实际上解决了以往对我来说这些问题，请务必在完成这些类型的更改后重新启动服务器，并清理项目，服务器和服务器工作目录（I “M通过月食我的Tomcat服务器）
• 如果你继续运行到问题，并相信它可能是配置上这样做，使用turnkey

Answer 2

使用Spring-FLEX/MySQL的/ BlazeDS的4

在库需要罐子

sping-flex-core-1.5 
mysql-connector-java-5.1.10 
org.springframework.beans-3.0.5.RELEASE 
org.springframework.context-3.0.5.RELEASE 
org.springframework.jdbc-3.0.5.RELEASE..etc 

创建雇员VO的Actionscript

[Bindable] 
[RemoteClass (alias="com.model.employee.Employee")] 
public class Employee 

爪哇侧封装com.model.employee;

Employee.java

EmployeeService.java（接口）.. getEmployeeById（INT ID）

EmployeeServiceImpl.java

@Service("employeeService") 
@RemotingDestination(channels = { "my-amf", "my-secure-amf" }) 
public class EmployeeServiceImpl implements EmployeeService { 

private final DataSource dataSource; 

public UserServiceImpl(DataSource dataSource) { 
    this.dataSource = dataSource; 
} 

@RemotingInclude 
public Employee getEmployeeById(int id) { 
    Employee employee= new Employee(); 
    Connection c = null; 
    try { 
     c = this.dataSource.getConnection(); 
     PreparedStatement ps = c.prepareStatement("SELECT * FROM employee WHERE employee_id=?"); 
     ps.setInt(1, id); 
     ResultSet rs = ps.executeQuery(); 
     if (rs.next()) { 
      employee= new Employee(); 
      employee.setEmployeeId(rs.getInt("employee_id")); 
      employee.setEmployeeName(rs.getString("employee_name")); 
     } 
    } catch (Exception e) { 
     e.printStackTrace(); 
     throw new RuntimeException(e); 
    } 
    return employee; 
} 

地方在遵守类WEB-INF /类

WEB-INF/appicationContext.xml

不需要remote-config。xml

启动tomcat，应该看到 信息：已成功启动远程处理目标'employeeService' 。

IN MMXL [Bindable] private var empl：Employee;

使用resultHandler定义RemoteObject roEmp 调用roEmp.getEmployeeById（id） empl = event.result as Employee;
