1.引入相关的jar:
2.MapListHandler的使用，将结果集转换为List<Map<String,Object>>
@Before
public void init() throws SQLException, ClassNotFoundException{
String driverClass="oracle.jdbc.driver.OracleDriver";
String url="jdbc:oracle:thin:@192.168.233.134:1521:orcl";
String username="cnmef";
String password="cnmef";
Class.forName(driverClass);
connection=DriverManager.getConnection(url,username,password);
}
/**
* 测试apache中dbUtils的mapListHandler的使用
* @throws SQLException
*/
@Test
public void MapListHandlerTest() throws SQLException{
String sql="select " +
"t1.id as \"id\","+
" t1.nofficeid as nofficeid, "+
" t1.ncurrencyid as \"ncurrencyid\", "+
" t1.transaction_num as \"transactionNum\", "+
" t1.interest_start as \"interestStart\", "+
" t1.interest_end as \"interestEnd\","+
" t1.margin_amount as \"marginAmount\", "+
" t1.abstract as \"summary\","+
" t1.ncontractid as \"ncontractId\","+
" t1.in_account as \"inAccount\","+
" t1.out_account as \"outAccount\" ,"+
" t1.inputuserid as \"inputuserid\","+
" t1.checkuserid as \"checkuserid\","+
" t1.checkdate as \"checkdate\","+
" (select t2.id from sett_subaccount t2 where t2.naccountid=t1.in_account and rownum=1 ) as \"subInAccountId\","+
" (select t3.id from sett_subaccount t3 where t3.naccountid=t1.out_account and rownum=1 ) as \"subOutAccountId\","+
" t1.margin_amount as \"marginAmount\" "+
" from sett_depositbatchreview t1 " ;
QueryRunner queryRunner=new QueryRunner();
List<Map<String,Object>> map=queryRunner.query(connection, sql, new MapListHandler());
for(Map<String,Object> temp:map){
System.out.println(temp);
}
}
@After
public void close(){
try{
if(connection!=null){
connection.close();
}
}catch(Exception e){
e.printStackTrace();
}
}
3.BeanListHandler的使用,返回List<Bean>:
@Before
public void init() throws SQLException, ClassNotFoundException{
String driverClass="oracle.jdbc.driver.OracleDriver";
String url="jdbc:oracle:thin:@192.168.233.134:1521:orcl";
String username="cnmef";
String password="cnmef";
Class.forName(driverClass);
connection=DriverManager.getConnection(url,username,password);
}
/**
* 测试apache中dbUtils的mapListHandler的使用
* @throws SQLException
*/
@Test
public void BeanListHandlerTest() throws SQLException{
String sql="select " +
"t1.id as \"id\","+
" t1.nofficeid as nofficeid, "+
" t1.ncurrencyid as \"ncurrencyid\", "+
" t1.transaction_num as \"transactionNum\", "+
" t1.interest_start as \"interestStart\", "+
" t1.interest_end as \"interestEnd\","+
" t1.margin_amount as \"marginAmount\", "+
" t1.abstract as \"summary\","+
" t1.ncontractid as \"ncontractId\","+
" t1.in_account as \"inAccount\","+
" t1.out_account as \"outAccount\" ,"+
" t1.inputuserid as \"inputuserid\","+
" t1.checkuserid as \"checkuserid\","+
" t1.checkdate as \"checkdate\","+
" (select t2.id from sett_subaccount t2 where t2.naccountid=t1.in_account and rownum=1 ) as \"subInAccountId\","+
" (select t3.id from sett_subaccount t3 where t3.naccountid=t1.out_account and rownum=1 ) as \"subOutAccountId\","+
" t1.margin_amount as \"marginAmount\" "+
" from sett_depositbatchreview t1 ";
QueryRunner queryRunner=new QueryRunner();
List<MarginAccountVo> map=queryRunner.query(connection, sql, new BeanListHandler<MarginAccountVo>(MarginAccountVo.class));
for(MarginAccountVo temp:map){
System.out.println(temp);
}
}
@After
public void close(){
try{
if(connection!=null){
connection.close();
}
}catch(Exception e){
e.printStackTrace();
}
}
4.测试MapHandler:返回Map<String,Object>
@Before
public void init() throws SQLException, ClassNotFoundException{
String driverClass="oracle.jdbc.driver.OracleDriver";
String url="jdbc:oracle:thin:@192.168.233.134:1521:orcl";
String username="cnmef";
String password="cnmef";
Class.forName(driverClass);
connection=DriverManager.getConnection(url,username,password);
}
/**
* 测试apache中dbUtils的mapListHandler的使用
* @throws SQLException
*/
@Test
public void MapHandlerTest() throws SQLException{
String sql="select " +
"t1.id as \"id\","+
" t1.nofficeid as nofficeid, "+
" t1.ncurrencyid as \"ncurrencyid\", "+
" t1.transaction_num as \"transactionNum\", "+
" t1.interest_start as \"interestStart\", "+
" t1.interest_end as \"interestEnd\","+
" t1.margin_amount as \"marginAmount\", "+
" t1.abstract as \"summary\","+
" t1.ncontractid as \"ncontractId\","+
" t1.in_account as \"inAccount\","+
" t1.out_account as \"outAccount\" ,"+
" t1.inputuserid as \"inputuserid\","+
" t1.checkuserid as \"checkuserid\","+
" t1.checkdate as \"checkdate\","+
" (select t2.id from sett_subaccount t2 where t2.naccountid=t1.in_account and rownum=1 ) as \"subInAccountId\","+
" (select t3.id from sett_subaccount t3 where t3.naccountid=t1.out_account and rownum=1 ) as \"subOutAccountId\","+
" t1.margin_amount as \"marginAmount\" "+
" from sett_depositbatchreview t1 where t1.id=? ";
QueryRunner queryRunner=new QueryRunner();
/*
* queryRunner.query(connection,sql,ResultSetHandler<T>,params);
*/
Map<String,Object> map=queryRunner.query(connection, sql, new MapHandler(),1);
System.out.println(map);
}
@After
public void close(){
try{
if(connection!=null){
connection.close();
}
}catch(Exception e){
e.printStackTrace();
}
}
5.测试BeanHandler:返回javaBean
@Before
public void init() throws SQLException, ClassNotFoundException{
String driverClass="oracle.jdbc.driver.OracleDriver";
String url="jdbc:oracle:thin:@192.168.233.134:1521:orcl";
String username="cnmef";
String password="cnmef";
Class.forName(driverClass);
connection=DriverManager.getConnection(url,username,password);
}
/**
* 测试apache中dbUtils的mapListHandler的使用
* @throws SQLException
*/
@Test
public void BeanHandlerTest() throws SQLException{
String sql="select " +
"t1.id as \"id\","+
" t1.nofficeid as nofficeid, "+
" t1.ncurrencyid as \"ncurrencyid\", "+
" t1.transaction_num as \"transactionNum\", "+
" t1.interest_start as \"interestStart\", "+
" t1.interest_end as \"interestEnd\","+

" t1.abstract as \"summary\","+
" t1.ncontractid as \"ncontractId\","+

" from sett_depositbatchreview t1 where t1.id=1 ";
QueryRunner queryRunner=new QueryRunner();
MarginAccountVo bean=queryRunner.query(connection, sql, new BeanHandler<MarginAccountVo>(MarginAccountVo.class));
System.out.println(bean);
}
@After
public void close(){
try{
if(connection!=null){
connection.close();
}
}catch(Exception e){
e.printStackTrace();
}
}
