1.在application.properties中,添加jndi配置,如下图
2.新建dataSourceConfig类
3.dataSourceConfig类详细代码,这里只贴出其中一个,多个数据源类似配置,只需更改 basePackages 路径和@Value("${spring.datasource.source1.jndi-name}"),以及下面名称带test1前缀的地方,不要和其他dataSourceConfig重名
@Configuration //注册到springboot 容器中
@MapperScan(basePackages = "对应的Mapper包路径",sqlSessionTemplateRef = "test1SqlSessionTemplate")
public class DataSource1Config {
//application.properties中的jndi名称
@Value("${spring.datasource.source1.jndi-name}")
private String jndiName;
@Bean(name = "test1DataSource",destroyMethod = "") // destroy method is disabled for Weblogic update app ability
@ConfigurationProperties(prefix = "spring.datasource.bigdata")
public DataSource bigdataDs() throws NamingException {
JndiObjectFactoryBean bean=new JndiObjectFactoryBean();
bean.setJndiName(jndiName);
bean.setProxyInterface(DataSource.class);
bean.setLookupOnStartup(false);
bean.afterPropertiesSet();
return (DataSource) bean.getObject();
}
@Bean(name = "test1SqlSessionFactory")
public SqlSessionFactory testSqlSessionFactory(@Qualifier("test1DataSource") DataSource dataSource) throws Exception {
SqlSessionFactoryBean bean = new SqlSessionFactoryBean();
bean.setDataSource(dataSource);
//加载其他文件,如mapper.xml
// bean.setMapperLocations(new PathMatchingResourcePatternResolver().getResources("classpath:mybatis/mapper/test1/*.xml"));
return bean.getObject();
}
//事务管理
@Bean(name = "test1TransactionManager")
public DataSourceTransactionManager testTransactionManager(@Qualifier("test1DataSource") DataSource dataSource) {
return new DataSourceTransactionManager(dataSource);
}
@Bean(name = "test1SqlSessionTemplate")
public SqlSessionTemplate testSqlSessionTemplate(@Qualifier("test1SqlSessionFactory") SqlSessionFactory sqlSessionFactory) throws Exception {
return new SqlSessionTemplate(sqlSessionFactory);
}
}
4.打开tomcat目录下context.xml文件,添加以下配置,多个数据源写多个Resource即可,注意name需要和application.properties配置的名称一致
<Resource name="jdbc/数据库名称" auth="Container" type="javax.sql.DataSource"
maxTotal="100" maxIdle="30" maxWaitMillis="10000"
username="javauser" password="javadude" driverClassName="com.mysql.jdbc.Driver"
url="jdbc:mysql://localhost:3306/javatest"/>
5.打成war包,部署到tomcat服务器运行,注意查看启动日志
