【问题描述】:
我试图按照以下示例使用 jdbcdao 访问数据库: http://www.mkyong.com/spring/spring-jdbctemplate-jdbcdaosupport-examples/
userdao、userdaoimpl、daocontext和datacontext.xml如下:
DAOIMPL
public class UserDAOImpl extends JdbcDaoSupport implements UserDAO {
/*Creates User */
public void insertUser(User user){
String sql = "INSERT INTO Users " +
"(id, username, password,role) VALUES (?, ?, ?,?)";
getJdbcTemplate().update(sql, new Object[] { user.getUserId(),
user.getUserName(),user.getPassWord()
});
}
}
道
import java.util.List;
import spring.web.models.User;
public interface UserDAO {
public void insertUser(User user);
}
DAOCONTEXT.XML
<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://www.springframework.org/schema/beans
http://www.springframework.org/schema/beans/spring-beans-4.0.xsd">
<bean id="userDAO" class="spring.web.dao.impl.UserDAOImpl">
<property name="primaryDataSource" ref="oracleDataSource" />
</bean>
</beans>
数据上下文.XML
<?xml version="1.0"?>
<beans
xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-4.0.xsd"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns="http://www.springframework.org/schema/beans">
<bean id="oracleDataSource" class="org.springframework.jdbc.datasource.DriverManagerDataSource">
<property value="oracle.jdbc.OracleDriver" name="driverClassName" />
<property value="jdbc:oracle:thin:@192.168.72.68:1521:d2he"
name="url" />
<property value="aaryal_1" name="username" />
<property value="oracle" name="password" />
</bean>
</beans>
我遇到的错误如下:
org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'userDAO' defined in class path resource [dao-context.xml]:
Error setting property values; nested exception is org.springframework.beans.NotWritablePropertyException:
Invalid property 'primaryDataSource' of bean class [spring.web.dao.impl.UserDAOImpl]:
Bean property 'primaryDataSource' is not writable or has an invalid setter method.
Does the parameter type of the setter match the return type of the getter?
请告诉我我错过了什么。
【问题讨论】:
-
JdbcDaoSupporthas not propertyprimaryDataSource。将其更改为dataSource,这是JdbcDaoSupport的可设置属性。你不能只是弥补属性。即使您链接的示例也使用dataSource
