沿途的风景美不胜收，真是让人流连忘返。人生就像一场旅行，不知道在下一站邂逅什么样的人，发生怎么样的故事!
数据库中有下划线的字段在实体中应采用驼峰命名法，如P_NAME对应pName,实例如下：
1.XML文件中SQL语句配置（Geteway.xml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.soecode.hbdw.gateway.dao.GatewayDao">
<cache></cache>
<!-- 目的：为dao接口方法提供sql语句配置 -->
<select id="queryById" resultType="Gateway" parameterType="int">
<!-- 具体的sql -->
SELECT
*
FROM
P_GATEWAY
WHERE
GATEWAY_ID = #{gatewayId}
</select>
<select id="queryByName" resultType="Gateway" parameterType="java.lang.String">
<!-- 具体的sql -->
SELECT
*
FROM
P_GATEWAY
WHERE
GATEWAY_NAME=#{gatewayName}
</select>
<delete id="delGateway" parameterType="java.lang.Integer">
DELETE
FROM
P_GATEWAY
WHERE
GATEWAY_ID = #{gatewayId}
</delete>
<update id="updateGateway" >
<!-- ignore 主键冲突，报错 -->
UPDATE P_GATEWAY
SET
GATEWAY_NAME= #{gatewayName},
GATEWAY_NUM= #{gatewayNum},
GATEWAY_NATURE= #{gatewayNature},
GATEWAY_SUPPLY= #{gatewaySupply},
REMARK= #{remark}
WHERE
GATEWAY_ID = #{gatewayId}
</update>
</mapper>
2.entity实体配置（Gateway.java文件）
package com.soecode.hbdw.gateway.entity;
import java.io.Serializable;
import java.util.Date;
public class Gateway implements Serializable{
/**
*
*/
private static final long serialVersionUID = 1L;
private int gatewayId;
private String gatewayName;
private String gatewayNum;
private String gatewayNature;
private String gatewaySupply;
private String remark;
public int getGatewayId() {
return gatewayId;
}
public void setGatewayId(int gatewayId) {
this.gatewayId = gatewayId;
}
public String getGatewayName() {
return gatewayName;
}
public void setGatewayName(String gatewayName) {
this.gatewayName = gatewayName;
}
public String getGatewayNum() {
return gatewayNum;
}
public void setGatewayNum(String gatewayNum) {
this.gatewayNum = gatewayNum;
}
public String getGatewayNature() {
return gatewayNature;
}
public void setGatewayNature(String gatewayNature) {
this.gatewayNature = gatewayNature;
}
public String getGatewaySupply() {
return gatewaySupply;
}
public void setGatewaySupply(String gatewaySupply) {
this.gatewaySupply = gatewaySupply;
}
public String getRemark() {
return remark;
}
public void setRemark(String remark) {
this.remark = remark;
}
public static long getSerialversionuid() {
return serialVersionUID;
}
@Override
public String toString() {
return "Gateway [gatewayId=" + gatewayId + ", gatewayName="
+ gatewayName + ", gatewayNum=" + gatewayNum
+ ", gatewayNature=" + gatewayNature + ", gatewaySupply="
+ gatewaySupply + ", remark=" + remark + "]";
}
}

以上就是Oracle在Mybatis中SQL语句的配置方法。口是心非在临床上的表现，不是结结巴巴，而是口口声声。更多关于Oracle在Mybatis中SQL语句的配置方法请关注haodaima.com其它相关文章！
