Webservice_23_SOAP的基于契约优先开发用户管理_添加异常

非常感谢孙浩老师。

为add和login方法增加异常处理。

先增加UserException.java

package cn.lichen.exception;

public class UserException extends Exception {


	public UserException() {
	}

	public UserException(String message) {
		super(message);
	}

	public UserException(Throwable cause) {
		super(cause);
	}

	public UserException(String message,Throwable cause) {
		super(message,cause);
	}

	public UserException(String message,Throwable cause,boolean enableSuppression,boolean writableStackTrace) {
		super(message,cause,enableSuppression,writableStackTrace);
	}

}

使用wsImport导出Java文件，所有拷贝到客户端，IMyService.java拷贝到服务端。

修改IMyService：

修改：

为：

为实现类增加异常扑获处理：

public void add(User user) throws UserException {
		if (users.containsKey(user.getUsername()))
			throw new UserException("用户名已经被占用了");
		users.put(user.getUsername(),user);
	}

	public User login(String username,String password) throws UserException {
		if (!users.containsKey(username))
			throw new UserException("用户不存在");
		User user = users.get(username);
		if (!password.equals(user.getPassword()))
			throw new UserException("用户密码不正确!");
		return user;
	}

服务实现类增加异常：

	@Override
	public void add(User user) throws UserException{
		userdao.add(user);
	}

	@Override
	public User login(String username,String passwrod) throws UserException{
		return userdao.login(username,passwrod);
	}

?

客户端测试方法：

	@Test
	public void testAdd(){
		
		try {
			User user = new User();
			user.setUsername("lisi");
			user.setNickname("李四");
			user.setPasswrod("123");
			service.add(user);
		} catch (UserException_Exception e) {
			System.out.println(e.getMessage());
		}
	}
	
	@Test
	public void testLogin(){
		try {
			System.out.println(service.login("fds","78").getNickname());
		} catch (UserException_Exception e) {
			System.out.println(e.getMessage());
		}
	}

?

结果：

客户端控制台：

服务端控制台：
