刚学注解,遇到问题,求解释
strut2的action里面:
[code=java]
@Namespace("/acctuser")
@Results( { @Result(name = CrudActionSupport.OK, location = "acctuser",type="chain") })
@Component("acctuser")
@Scope("prototype")
@SuppressWarnings("serial")
public class AcctuserAction extends CrudActionSupport <AcctUser> {
@Autowired
private IAcctUserService iAcctUserService;
[/code]
service里面：
[code=java]
@Service("iAcctUserService")
@Transactional
public class AcctUserService implements IAcctUserService{
@Autowired
private IAcctUserDao iAcctUserDao;
[/code]
dao里面：
[code=java]
@Repository("iAcctUserDao")
public class AcctUserDao extends BaseDao implements IAcctUserDao{
public boolean login(String uname, String upass) {
String sql = "select count(*) from acct_user where login_name='"
+ uname + "' and password='" + upass + "'";
int count=jdbcTemplate.queryForInt(sql);
if(count>0){
return true;
}
return false;
}
[/code]
basedao：
[code=java]
public class BaseDao {
@Autowired
public JdbcTemplate jdbcTemplate;
[/code]
application.xml里面
<bean class="org.springframework.beans.factory.config.PropertyPlaceholderConfigurer"> <property name="systemPropertiesModeName" value="SYSTEM_PROPERTIES_MODE_OVERRIDE" /> <property name="ignoreResourceNotFound" value="true" /> <property name="locations"> <list> <value>classpath*:/util.properties</value> </list> </property> </bean> <!-- 使用annotation 自动注册bean,并保证@Required,@Autowired的属性被注入 --> <context:component-scan base-package="com.jw" /> <!-- 数据源配置,使用应用内的DBCP数据库连接池 --> <bean name="dataSource" class="org.apache.commons.dbcp.BasicDataSource" destroy-method="close"> <property name="driverClassName" value="${mysql.driver}" /> <property name="url" value="${mysql.url}" /> <property name="username" value="${mysql.username}" /> <property name="password" value="${mysql.password}"></property> </bean> <!-- 使用annotation定义事务 --> <tx:annotation-driven proxy-target-class="true" /> <bean name="jdbcTemplet" class="org.springframework.jdbc.core.JdbcTemplate"> <property name="dataSource" ref="dataSource" /> </bean>
