第一部分

測試情況如下:

maven修改

com.alibaba

druid

1.1.10

實體類

@Table(name = "dpcenter.xeuser")

public class OUser {

private String userid;

private String username;

...

}

測試代碼

public static void main(String[] args) {

OracleStyle style=new OracleStyle();

ConnectionSource cs = ConnectionSourceHelper.getSingle(druidSource());

SQLLoader loader = new ClasspathLoader("/org/beetl/sql/test");

DebugInterceptor debug = new DebugInterceptor(OracleQuickTest.class.getName());

Interceptor[] inters = new Interceptor[]{ debug};

final SQLManager sql = new SQLManager(style,loader,cs,new UnderlinedNameConversion(), inters);

OUser ou=new OUser();

ou.setUserid("hp-test");

ou.setUsername("test");

OUserDao oUserDao=sql.getMapper(OUserDao.class);

oUserDao.insert(ou);

}

public static DataSource druidSource() {

com.alibaba.druid.pool.DruidDataSource ds = new com.alibaba.druid.pool.DruidDataSource();

ds.setUrl("jdbc:oracle:thin:@192.168.1.4:1521:orcl");

ds.setUsername("dpmanage");

ds.setPassword("dpmanage");

ds.setDriverClassName("oracle.jdbc.driver.OracleDriver");

return ds;

}

第二部分

修改beetlsql代碼MetadataManager

private void setDefaultSchema(Connection conn) throws SQLException{

try {

this.defalutCatalog = conn.getCatalog();

}catch(Throwable e) {

// jdbc低版本不支持

e.printStackTrace();

}

try{

this.defaultSchema = conn.getSchema();

}catch(Exception e){

// jdbc低版本不支持

String dbName = sm.getDbStyle().getName();

if(dbName.equals("postgres")){

defaultSchema = "public";

}else if(dbName.equals("sqlserver")){

defaultSchema="dbo";

}else if(dbName.equals("oracle")){

defaultSchema = conn.getMetaData().getUserName();

}else{

defaultSchema = null;

}

}

}

使用版本 2.10.29

總結

1 如果使用beetlsql-2.10.29+druid-1.1.10 會產生SQLFeatureNotSupportedException，原因是catch了Error沒有catch Exception

2 如果修改了1中的Error為Exception可啟動程序

3 oracle中使用@Table(name="{schema}.{tableName}")時會產生錯誤，分析原因是獲取tableName時會截取"."后面的字符串作為tableName。本來想修改一下然后提交給作者，但考慮整體架構擴展性還是提交給issue吧
