bboss持久层快速入门教程，快速搭建bboss持久层的开发环境，并编写一个简单的实例，实例中涉及以下功能点：
-
动态启动数据源（基于apache dbcp2连接池组件）
-
做一个简单的增删改查操作例子
持久层环境搭建
首先在项目中导入bboss 持久层包：
maven坐标
<dependency>
<groupId>com.bbossgroups</groupId>
<artifactId>bboss-persistent</artifactId>
<version>5.0.7.2</version>
</dependency>
gradle坐标
compile 'com.bbossgroups:bboss-persistent:5.0.7.2'
首先搭建持久层demo开发环境，下载bboss最佳实践：
git clone -b master --depth 1 https://github.com/bbossgroups/bestpractice.git
下载完毕后通过gradle插件将bestpractice导入eclipse即可：
启动一个名称叫test的oracle数据源：
SQLUtil.startPool("test",//数据源名称
"oracle.jdbc.driver.OracleDriver",//oracle驱动
"jdbc:oracle:thin:@(description=(address_list=(load_balance=off)(failover=on)"
+ "(address=(protocol=tcp)(host=192.168.1.226)(port=1521))(address=(protocol=tcp)(host=192.168.1.227)(port=1521)))"
+ "(connect_data=(service_name=PF1)(failover_mode=(type=select)(method=basic)(RETRIES=180)(DELAY=5))))",//oracle rac链接串
"mdm","123456",//数据库账号和口令
"select 1 from dual" //数据库连接校验sql
);//初始化数据源
数据源启动后，接下来就可以在test数据源上执行相关的操作：
List<String> data = SQLExecutor.queryListWithDBName(String.class,"test","select MODULE_ID from TB_MODULE_INFO where MODULE_URL like ?","%/CrmAccount/%");
int aid =SQLExecutor.queryObjectWithDBName(int.class, "test","select max(to_number(AUTH_ID)) from TB_MODULE_AUTH");
aid ++;
for(String mid:data)
{
SQLExecutor.insertWithDBName("test", "insert into TB_MODULE_AUTH(AUTH_ID,ADMIN_ID,MODULE_ID) values(?,'23',?)", aid+"",mid);
aid = aid+1;
}
SQLExecutor.insertWithDBName("test", "insert into TB_MODULE_AUTH(AUTH_ID,ADMIN_ID,MODULE_ID) values(?,'23',?)", aid+"","11");
再看一个基于sqlite的数据库的判断表不存在并建表的示例：
//启动sqlite数据源gencode
SQLUtil.startPool("gencode","org.sqlite.JDBC","jdbc:sqlite://"+dbpath,"root","root",
"select 1"
);
//判断数据源gencode中对于的表BBOSS_GENCODE是否存在，不存在则创建
String exist = "select 1 from BBOSS_GENCODE";
try {
SQLExecutor.queryObjectWithDBName(int.class,"gencode", exist);
} catch (Exception e) {
String tsql = "create table BBOSS_GENCODE (ID string,TABLENAME string,DBNAME string,FIELDINFOS TEXT,AUTHOR string,"
+ "COMPANY string,"
+ "CREATETIME number(10),"
+ "UPDATETIME number(10),"
+ "CONTROLPARAMS TEXT,"
+ " PRIMARY KEY (ID))";
try {
SQLExecutor.updateWithDBName("gencode",tsql);
} catch (SQLException e1) {
e1.printStackTrace();
}
}
完整的测试用例请看工程中的CustomPoolTest.java文件。
