Question

我是MyBatis的新手。我正在使用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，我得到了错误

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.

但如果我传递1个参数，我没有错误。这是我的档案。

<?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界面是

@Repository
public interface MassPaymentDaoMapper {



     public List<MassPaymentFile> getLastMassPaymentRecords(Map<String,Object> params);


}

我也试过了下一个变种

@Repository
    public interface MassPaymentDaoMapper {



         public List<MassPaymentFile> getLastMassPaymentRecords(@Param("user_id") int userId, @Param("kount") int count);


    }

但结果是一样的。我的错误在哪里？请帮帮我

我发现了我的错误。

我将sql语句包含在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>

Mybatis传递多个值进行查询
