這篇文章主要介紹了Oracle在Mybatis中SQL語(yǔ)句的配置 ,非常不錯(cuò)，具有參考借鑒價(jià)值，需要的朋友可以參考下

數(shù)據(jù)庫(kù)中有下劃線的字段在實(shí)體中應(yīng)采用駝峰命名法，如P_NAME對(duì)應(yīng)pName,實(shí)例如下：

1.XML文件中SQL語(yǔ)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：為dao接口方法提供sql語(yǔ)句配置 -->
 <select id="queryById" resultType="Gateway" parameterType="int">
 <!-- 具體的sql -->
 SELECT 
   *
 FROM
  P_GATEWAY
 WHERE
  GATEWAY_ID = #{gatewayId}
 </select>
 <select id="queryByName" resultType="Gateway" parameterType="java.lang.String">
 <!-- 具體的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 主鍵沖突，報(bào)錯(cuò) -->
   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實(shí)體配置（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 + "]";
 }
}
