Oracle在Mybatis中SQL语句的配置方法

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"?>


 
 
 
 
 SELECT 
   *
 FROM
  P_GATEWAY
 WHERE
  GATEWAY_ID = #{gatewayId}
 
 
 
 SELECT
  *
 FROM
  P_GATEWAY
 WHERE
  GATEWAY_NAME=#{gatewayName}
 
 
   DELETE 
   FROM 
   P_GATEWAY
   WHERE
   GATEWAY_ID = #{gatewayId}
 
 
 
   UPDATE P_GATEWAY
   SET
   GATEWAY_NAME= #{gatewayName},
   GATEWAY_NUM= #{gatewayNum},
   GATEWAY_NATURE= #{gatewayNature},
   GATEWAY_SUPPLY= #{gatewaySupply},
   REMARK= #{remark} 
   WHERE
   GATEWAY_ID = #{gatewayId}
  

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 + "]";
 }
}
