我是 MyBatis 的新手。我使用 mybatis 3.1.1 版本作为 DAO 实现。
我想将 2 个参数传递给我的查询。当我尝试这样做时出现错误
Related cause: org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'massPaymentDaoMapper' defined in file [D:\work\projects\paymentgw\target\PaymentGateway-1.0\WEB-INF\classes\com\company\paymentgateway\dao\MassPaymentDaoMapper.class]: Invocation of init method failed; nested exception is java.lang.IllegalArgumentException: org.apache.ibatis.builder.BuilderException: Error creating document instance. Cause: org.xml.sax.SAXParseException; lineNumber: 45; columnNumber: 45; The content of elements must consist of well-formed character data or markup.
但是如果我传递 1 个参数,我就不会收到错误。这是我的文件。
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE mapper PUBLIC "-//mybatis.org//DTD Mapper 3.0//EN"
"http://mybatis.org/dtd/mybatis-3-mapper.dtd">
<mapper namespace="com.company.paymentgateway.dao.MassPaymentDaoMapper">
<select id="getLastMassPaymentRecords" resultType="MassPaymentFile" parameterType="map" >
SELECT
file_id,
file_name,
record_count,
error_count,
status,
user_id
FROM mass_payment_protocol
WHERE user_id=#{user_id} AND rownum<=#{kount, javaType=Integer, jdbcType=NUMERIC}
ORDER BY created desc
</select>
</mapper>
我的java接口(interface)是
@Repository
public interface MassPaymentDaoMapper {
public List<MassPaymentFile> getLastMassPaymentRecords(Map<String,Object> params);
}
我还尝试了下一个变体
@Repository
public interface MassPaymentDaoMapper {
public List<MassPaymentFile> getLastMassPaymentRecords(@Param("user_id") int userId, @Param("kount") int count);
}
但是结果是一样的。我的错误在哪里?请帮助我
最佳答案
我发现了我的错误。
我将sql语句包含到CDATA中
<select id="getLastMassPaymentRecords" resultType="MassPaymentFile" parameterType="map" >
<![CDATA[
SELECT
file_id,
file_name,
record_count,
error_count,
status,
user_id
FROM mass_payment_protocol
WHERE user_id=#{user_id} AND rownum<=#{count}
ORDER BY created desc
]]>
</select>
