tomcat數據源配置

<resultMap type="java.util.Map" id="resultjcm">

<result property="FLD_NUMBER" column="FLD_NUMBER" javaType="double" jdbcType="NUMERIC"/>

<result property="FLD_VARCHAR" column="FLD_VARCHAR" javaType="string" jdbcType="VARCHAR"/>

<result property="FLD_DATE" column="FLD_DATE" javaType="java.sql.Date" jdbcType="DATE"/>

<result property="FLD_INTEGER" column="FLD_INTEGER" javaType="int" jdbcType="INTEGER"/>

<result property="FLD_DOUBLE" column="FLD_DOUBLE" javaType="double" jdbcType="DOUBLE"/>

<result property="FLD_LONG" column="FLD_LONG" javaType="long" jdbcType="INTEGER"/>

<result property="FLD_CHAR" column="FLD_CHAR" javaType="string" jdbcType="CHAR"/>

<result property="FLD_BLOB" column="FLD_BLOB" javaType="byte[]" jdbcType="BLOB" />

<result property="FLD_CLOB" column="FLD_CLOB" javaType="string" jdbcType="CLOB"/>

<result property="FLD_FLOAT" column="FLD_FLOAT" javaType="float" jdbcType="FLOAT"/>

<result property="FLD_TIMESTAMP" column="FLD_TIMESTAMP" javaType="java.sql.Timestamp" jdbcType="TIMESTAMP"/>

</resultMap>

2）和阿里巴巴數據庫鏈接池集成

 2.1）maven的依賴管理

<dependency>             <groupId>com.alibaba</groupId>             <artifactId>druid</artifactId>             <version>1.0.14</version>         </dependency>         <dependency>             <groupId>mysql</groupId>             <artifactId>mysql-connector-java</artifactId>             <version>5.1.28</version>             <scope>runtime</scope>         </dependency>

1.2 建立數據源的Factory

public class DruidDataSourceFactory implements DataSourceFactory {     private DataSource dataSource;     @Override     public void setProperties(Properties properties) {         try {             this.dataSource = com.alibaba.druid.pool.DruidDataSourceFactory.createDataSource(properties);         } catch (final RuntimeException e) {             throw e;         } catch (final Exception e) {             throw new RuntimeException("init datasource error", e);         }     }     @Override     public DataSource getDataSource() {         return this.dataSource;     } }

1.3配置mybatis的environment的數據源

<environment id="development">             <transactionManager type="JDBC" />             <dataSource type="packagename.persist.factory.DruidDataSourceFactory">                 <property name="driver" value="${jdbc.driver}" />                 <property name="url" value="${jdbc.url}" />                 <property name="username" value="${jdbc.username}" />                 <property name="password" value="${jdbc.password}" />                 <property name="initialSize" value="1" />                 <property name="minIdle" value="1" />                 <property name="maxActive" value="20" />                 <property name="maxWait" value="60000" />                 <property name="timeBetweenEvictionRunsMillis" value="60000" />                 <property name="minEvictableIdleTimeMillis" value="300000" />                 <property name="validationQuery" value="SELECT 'x'" />                 <property name="testWhileIdle" value="true" />                 <property name="testOnBorrow" value="false" />                 <property name="testOnReturn" value="false" />                 <property name="poolPreparedStatements" value="true" />                 <property name="maxPoolPreparedStatementPerConnectionSize" value="20" />                 <property name="filters" value="stat" />             </dataSource>         </environment>

<Context> <!-- 使用阿里巴巴的DruidDataSource配置針對Oracle數據庫的JNDI數據源 --> <Resource      name="jdbc/OracleDataSource"     factory="com.alibaba.druid.pool.DruidDataSourceFactory"     auth="Container"     type="javax.sql.DataSource"     driverClassName="oracle.jdbc.OracleDriver"     url="jdbc:oracle:thin:@192.168.1.229:1521:lead"     username="lead_oams"     password="p"     maxActive="50"     maxWait="10000"     removeabandoned="true"     removeabandonedtimeout="60"     logabandoned="false"     filters="stat"/>      <!-- 使用阿里巴巴的DruidDataSource配置針對MySQL數據庫的JNDI數據源 -->  <Resource      name="jdbc/MysqlDataSource"     factory="com.alibaba.druid.pool.DruidDataSourceFactory"     auth="Container"     type="javax.sql.DataSource"     driverClassName="com.mysql.jdbc.Driver"     url="jdbc:mysql://192.168.1.233:3306/lead_oams?useUnicode=true&amp;characterEncoding=utf-8"     username="lead_system"     password="password"     maxActive="50"     maxWait="10000"     removeabandoned="true"     removeabandonedtimeout="60"     logabandoned="false"     filters="stat"/>      <!--使用阿里巴巴的DruidDataSource配置針對SQLServer數據庫的JNDI數據源--> <Resource      name="jdbc/SqlServerDataSource"     auth="Container"     factory="com.alibaba.druid.pool.DruidDataSourceFactory"      type="javax.sql.DataSource"     driverClass="com.microsoft.sqlserver.jdbc.SQLServerDriver"     url="jdbc:sqlserver://192.168.1.61:1433;DatabaseName=gaclTest"     username="sa"      password="p@ssw0rd"     maxActive="50"     maxWait="10000"     removeabandoned="true"     removeabandonedtimeout="60"     logabandoned="false"     filters="stat"/> </Context>
