ibatis和json-lib應用

由於項目需要剛剛研究了一下ibatis和json-lib的配置和應用。

調試成功，寫下筆記以供大家分享和自己日後查閱

用到ibatis-2.3.4.726.jar這個包是獨立的

還有json-lib-2.3-jdk15.jar這個包需要一下幾個包也在才能使用

commons-beanutils-1.7.jar

commons-lang-2.0.jar

commons-logging-1.0.2.jar

ezmorph-1.0.6.jar

xom-1.1.jar

commons-collections-3.2.jar

還有連接oracle的包ojdbc14.jar

可以到http://www.docjar.com去下載包

現在講講ibatis的配置：

文件結構如下圖：

sqlMapConfig.xml內容爲

 

<?xml version="1.0" encoding="UTF-8"?>

<!DOCTYPE sqlMapConfig 

 PUBLIC "-//iBATIS.com//DTD SQL Map Config 2.0//EN" 

 "http://www.ibatis.com/dtd/sql-map-config-2.dtd">

<sqlMapConfig>

<properties resource="CCH/Map/SqlMapConfig11.properties" />

<settings cacheModelsEnabled="true"

enhancementEnabled="true"

lazyLoadingEnabled="true"

errorTracingEnabled="true"

maxRequests="32"

maxSessions="10"

maxTransactions="5"

useStatementNamespaces="false" />

<transactionManager type="JDBC">

<dataSource type="SIMPLE">

<property name="JDBC.Driver" value="${driver}" />

<property name="JDBC.ConnectionURL" value="${url}" />

<property name="JDBC.Username" value="${username}" />

<property name="JDBC.Password" value="${password}" />

</dataSource>

</transactionManager>

<sqlMap resource="CCH/Map/User.xml" />

</sqlMapConfig> 

 

 

SqlMapConfig11.properties的內容：

 

driver=oracle.jdbc.driver.OracleDriver

url=jdbc:oracle:thin:@IP:1521:orcl

username=username

password=password

 

 

 

 

user.xml的內容爲：

 

 

<?xml version="1.0" encoding="UTF-8"?>

<!DOCTYPE sqlMap

PUBLIC "-//iBATIS.com//DTD SQL Map 2.0//EN"

"http://www.ibatis.com/dtd/sql-map-2.dtd">

<sqlMap namespace="User">

<!--

Use primitive wrapper type (e.g. Integer) as parameter and allow

results to be auto-mapped results to Person object (Java Bean)

properties

-->

<resultMap id="userResult" class="CCH.Model.UserInfo">

   <result property="userId" column="userName"/>

   <result property="userName" column="userName1"/>

   </resultMap>

 

<insert id="insertUser" parameterClass="CCH.Model.UserInfo">

insert into cch_test(UserName,UserName1) values(#userId#,#userName#)

</insert>

<select id="selectUser" resultMap="userResult" >

select * from cch_test

</select>

</sqlMap>

 

 

myAppConf.java的內容爲：

 

 

package CCH.App;

 

import java.io.IOException;

import java.io.Reader;

 

import com.ibatis.common.resources.Resources;

import com.ibatis.sqlmap.client.SqlMapClient;

import com.ibatis.sqlmap.client.SqlMapClientBuilder;

 

public class MyAppConfig {

 

private static SqlMapClient client = null;

static {

try {

Reader reader = Resources.getResourceAsReader("CCH/Map/SqlMapConfig.xml");

client = SqlMapClientBuilder.buildSqlMapClient(reader);

} catch (IOException e) {

// TODO Auto-generated catch block

e.printStackTrace();

}

}

public static SqlMapClient getSqlMapClient(){

return client;

}

}

CCH.Model裏面的UserInfo.java的內容爲：

package CCH.Model;

public class UserInfo {

private String userId;

public String getUserId() {

return userId;

}

public void setUserId(String userId) {

this.userId = userId;

}

private String userName;

public String getUserName() {

return userName;

}

public void setUserName(String userName) {

this.userName = userName;

}

}

調用的部分代碼爲：

client= MyAppConfig.getSqlMapClient();

//client.insert("insertUser", userInfo);

List<UserInfo> list=client.queryForList("selectUser");

大家應該都能看懂。不足的地方還請留言說明。
