關於ssh 使用批註

在applicationContext.xml中加入下句，掃描@Respository  @Service  @Controller

<context:component-scan base-package="com.base.*" />

以登陸login爲例說明

@Controller("accountsController")
public class AccountsController extends BaseAction {
	//BaseAction 已經繼承了 ActionSupport
	@Resource
	AccountsService accountsService;
	
	public String login() throws Exception {
		String username = ServletActionContext.getRequest().getParameter("username");
		String password = ServletActionContextgetRequest().getParameter("password");
		Accounts accounts = accountsService.getAccountByUsername(username);
		System.out.println("PASSWORD:" + accounts.getPassword());		
		return "SUCCESS";
	}
}

@Service("accountsService")
@Lazy(true)
public class AccountsServiceImpl extends BaseServiceImpl<Accounts> implements AccountsService{
	protected AccountsDao accountsDao;
	
	@Resource
	public void setAccountsDao(AccountsDao accountsDao) {
		this.accountsDao = accountsDao;
		super.baseDao = accountsDao;
	}

	@Override
	public Accounts getAccountByUsername(String username) {
		List<Accounts> list = accountsDao.getObjectsByQuery("AND a.username = '" + username +"'");
		return list.get(0);
	}
	
	
}

@Repository
public class AccountsDaoImpl extends BaseDaoImpl<Accounts> implements AccountsDao{
	AccountsDaoImpl() {
		super(Accounts.class);<span style="white-space:pre">	// (Class<T> )entityClass = <span style="font-family: Arial, Helvetica, sans-serif;">Accounts.class</span>

	}
}

接下來是struts.xml的action配置，action的class是@Controller("accountsController")，method="login"是這個類中的方法

<package name="LoginActionPackage" namespace="/LoginManager" extends="struts-default">
	<action name="user_login" class="accountsController" method="login">
		<result name="success">/home.jsp</result>
		<result name="error">/login.jsp</result>
	</action>
</package>

然後是前臺的登錄請求

<form action="LoginManager/user_login.action" id="loginForm" method="post">
	<ol>
		<li><input type="text" name="username" id="username"/></li>
		<li><input type="password" name="password" id="password"/></li>
		<li><input type="submit" id="loginBtn" value="login"/></li>
	</ol>
</form>
