您好!在 iBATIS 中传递和返回自定义数组对象时,可以使用以下方法:
public class CustomArray {
private String[] array;
public String[] getArray() {
return array;
}
public void setArray(String[] array) {
this.array = array;
}
}
CREATE TYPE custom_array AS TABLE OF VARCHAR2(255);
CREATE TABLE custom_array_table (
id NUMBER PRIMARY KEY,
array_data custom_array
);
<result property="array" column="array_data" typeHandler="ArrayTypeHandler"/>
</parameterMap><select id="getCustomArray" parameterMap="CustomArrayMap" resultMap="CustomArrayMap">
SELECT array_data FROM custom_array_table WHERE id = #{id}
</select><insert id="insertCustomArray" parameterMap="CustomArrayMap">
INSERT INTO custom_array_table (id, array_data) VALUES (#{id}, #{array})
</insert>
CustomArray customArray = new CustomArray();
customArray.setArray(new String[]{"value1", "value2", "value3"});
SqlSession sqlSession = sqlSessionFactory.openSession();
CustomArrayMapper customArrayMapper = sqlSession.getMapper(CustomArrayMapper.class);
// 插入自定义数组对象
customArrayMapper.insertCustomArray(customArray);
// 获取自定义数组对象
CustomArray result = customArrayMapper.getCustomArray(1);
在上述示例中,我们使用了 iBATIS 的自定义类型处理器 ArrayTypeHandler
来处理自定义数组对象。同时,我们也演示了如何在 iBATIS 中传递和返回自定义数组对象。
