非全局jndi配置步骤 ：此种配置方式不需要在server.xml中配置数据源，而只在tomcat/conf/Catalina/localhost下的启动配置中配置即可。注意红色字体名称必须和相同。
0、需要在tomcat/common/lib下加入数据库连接的jar包
1、web.xml配置 <resource-ref> <description>my DB Connection</description> <res-ref-name>mydataSource </res-ref-name> <res-type>javax.sql.DataSource</res-type> <res-auth>Container</res-auth> </resource-ref> |
2、applicationContext.xml下配置
<bean id= "dataSource" class = "org.springframework.jndi.JndiObjectFactoryBean" > <property name= "jndiName" value= "java:comp/env/mydataSource " /> </bean> |
3、在tomcat的conf下的localhost下的配置如下
<?xml version= "1.0" encoding= "UTF-8" ?> <Context docBase= "F:/workspace/cuapp/WebRoot" path= "cuapp" reloadable= "false" > <Resource name= "mydataSource" auth= "Container" type= "javax.sql.DataSource" url= "jdbc:oracle:thin:@192.168.2.104:1521:ora10g" driverClassName= "oracle.jdbc.driver.OracleDriver" password= "aa" username= "aa" initialSize= "2" maxActive= "3" maxIdle= "1" minIdle= "1" maxWait= "10000" removeAbandoned= "true" logAbandoned= "true" removeAbandonedTimeout= "60" timeBetweenEvictionRunsMillis= "900000" minEvictableIdleTimeMillis= "1800000" numTestsPerEvictionRun= "100" validationQuery= "select count(0) from dual" poolPreparedStatements= "true" maxOpenPreparedStatements= "100" /> </Context> |
全局jndi配置 ：此种配置需要在server.xml中配置数据源。
0、需要在tomcat下加入数据库连接的jar包
1、web.xml配置 <resource-ref> <description>my DB Connection</description> <res-ref-name>mydataSource </res-ref-name> must be same as server.xml <res-type>javax.sql.DataSource</res-type> <res-auth>Container</res-auth> </resource-ref> |
2、applicationContext.xml下配置
<bean id= "dataSource" class = "org.springframework.jndi.JndiObjectFactoryBean" > <property name= "jndiName" value= "java:comp/env/mydataSource " /> </bean> |
3、server.xml中配置为
<!-- Global JNDI resources --> <GlobalNamingResources> <!-- Test entry for demonstration purposes --> <Environment name= "simpleValue" type= "java.lang.Integer" value= "30" /> <!-- Editable user database that can also be used by UserDatabaseRealm to authenticate users --> <Resource name= "UserDatabase" auth= "Container" type= "org.apache.catalina.UserDatabase" description= "User database that can be updated and saved" factory= "org.apache.catalina.users.MemoryUserDatabaseFactory" pathname= "conf/tomcat-users.xml" /> <Resource name= "mydataSource" auth= "Container" type= "javax.sql.DataSource" url= "jdbc:oracle:thin:@192.168.2.104:1521:ora10g" driverClassName= "oracle.jdbc.driver.OracleDriver" password= "aa" username= "aa" initialSize= "5" maxActive= "10" maxIdle= "5" minIdle= "2" maxWait= "10000" removeAbandoned= "true" logAbandoned= "true" removeAbandonedTimeout= "60" timeBetweenEvictionRunsMillis= "900000" minEvictableIdleTimeMillis= "1800000" numTestsPerEvictionRun= "100" validationQuery= "select count(0) from dual" poolPreparedStatements= "true" maxOpenPreparedStatements= "100" /> </GlobalNamingResources> |
4、tomcat/conf下localhost下的配置如下
<?xml version= "1.0" encoding= "UTF-8" ?> <Context docBase= "F:/workspace/cuapp/WebRoot" path= "xj-adminportal" reloadable= "false" > <ResourceLink name= "mydataSource " global= "mydataSource " type= "javax.sql.DataSource" /> </Context> |
