来项目内用的是普通数据源.考虑没有分布式的数据访问.就使用了apache-commons-dbcp.但是后来项目内要加一个第三方的报表制作工具.该工具强制要求使用JNDI来获得连接(该死的)没办法.只有加了.显将配置步骤和一个错误做笔记如下:
1. 环境: windowsXp系统.使用的是JBossGA-4.2.2 sqlserver2000.
项目架构是 Spring+ibatis+struts.
2. 配置步骤1 . 由于JBoss会自动查找server/default/deploy目录下的 **-ds.xml文件.并读取其中内容.来得到相应的DataSource,我的文件具体内容如下:
jdbc/DataSource jdbc:jtds:sqlserver://localhost:1433/fnx net.sourceforge.jtds.jdbc.Driver sa 1234 MS SQLSERVER2000
配置步骤2 . (有部分内容来自网上) 由于使用spring来获取jndi.所以实现了FacToryBean, InitializingBean
get/set方法没加
public class DataSourceFacToryBean implements FacToryBean, InitializingBean {/** 缓存数据源对象 */private DataSource dataSource;/** 是否jndi数据源 */private boolean jndi;/** 数据源的名字（如果是jndi数据源） */private String jndiName;/** jdbc驱动类(非jndi的情况) */private String driverClassName;/** 数据库的url(非jndi的情况) */private String url;/** 用户名(非jndi的情况) */private String username;/** 密码(非jndi的情况) */private String password;public void afterPropertiesSet() throws Exception { if (this.isJndi()) { if (!org.springframework.util.StringUtils.hasText(this.jndiName)) { throw new IllegalArgumentException("jndiName is required"); } } else { if (!org.springframework.util.StringUtils .hasText(this.driverClassName)) { throw new IllegalArgumentException( "driverClassName is required"); } if (!org.springframework.util.StringUtils.hasText(this.url)) { throw new IllegalArgumentException("url is required"); } if (!org.springframework.util.StringUtils.hasText(this.username)) { throw new IllegalArgumentException("username is required"); } if (!org.springframework.util.StringUtils.hasText(this.password)) { throw new IllegalArgumentException("password is required"); } } // 在初始化时就创建数据源 this.createDataSource();}public Object getObject() throws Exception { DataSource ds = this.createDataSource(); return ds;}public Class getObjectType() { return javax.sql.DataSource.class;}public boolean isSingleton() { return true;}protected DataSource createDataSource() { DataSource ds = this.dataSource; if (ds == null) { try { if (this.isJndi()) { ds = new JndiDataSourceSupport() .lookupDataSource(this.jndiName); } else { ds = new DriverManagerDataSource(driverClassName, url, username, password); } } catch (Throwable err) { throw new RuntimeException(err); } } this.dataSource = ds; return ds;}private class JndiDataSourceSupport extends JndiLocaTorSupport { public DataSource lookupDataSource(String jndiName) throws NamingException { return (DataSource) super.lookup(jndiName,getObjectType()); }}}
配置步骤3. spring的配置文件片段
class="org.springframework.beans.facTory.config.PropertyPlaceholderConfigurer"> classpath:config/jdbc.properties
设置步骤4 . jdbc.properties
#false 为开发时候使用的传统datasource 。为true为使用jndi得到datasource。建议开发时候使用前者
jdbc.IS_JNDI=truejdbc.jndiName=java:jdbc/DataSource#sqljdbc.driverClassName=net.sourceforge.jtds.jdbc.Driverjdbc.url=jdbc:jtds:sqlserver://localhost:1433/fnxjdbc.username=sajdbc.password=1234
设置步骤5 一些说明.上面绿色部分要相同.jndi的datasource采用的而是jdts.开始的时候总是有错.第一次无法的到连接.
刷新后就可以得到连接.百思不得其解.经过查找发现自己大意了.没有吧jdts的jar放在JBoss4.2.2GA/server/default/lib下面.解决和异常如下:
JBoss jndi jtds sqlserver2000 第一次错误得不到连接.然后刷新页面就ok的问题.
问题搞定.
就是jar没加对.
jdni属于容器的应该加在容器内.我们加载在项目内.当然第一次会出错.
然后第二次项目内的jar就会加载到容器你.所以就可用了.
应该在JBoss4.2.2GA/server/default/lib加数据库jar就可以了.
错误异常如下:
