Spring JDBCTemplate給出InvalidResultSetAccessException列索引無效

Question

我使用Spring的SimpleJDBCTemplate來訪問Oracle數據庫。這是我的代碼。

String sql = "SELECT from_bin_code FROM hbin_import_mapping"; 
return jt.query(sql, new BeanHbinImportMappingMapper(), (Object) null); 

行映射是：

public class BeanHbinImportMappingMapper 
    implements 
     RowMapper<BeanHbinImportMapping> { 
    public BeanHbinImportMapping mapRow(ResultSet rs, int rowno) 
     throws SQLException { 
     int fromBinCode = rs.getInt("from_bin_code"); 
//  char fromBinCodeChar = rs.getString("from_bin_code_char").charAt(0); 
//  boolean fromBinCodeAllowed = rs.getString("from_bin_code_allowed") 
//   .equals("Y") ? true : false; 
//  int oliBinCode = rs.getInt("oli_bin_code"); 
//  String oliBinQuality = rs.getString("oli_bin_quality"); 
//  String oliBinGroup = rs.getString("oli_bin_group"); 
//  String oliBinDesc = rs.getString("oli_bin_desc"); 
//  boolean olibinRef = rs.getString("oli_bin_ref").equals("Y") ? true 
//   : false; 

     BeanHbinImportMapping bean = new BeanHbinImportMapping(fromBinCode); 
//  BeanHbinImportMapping bean = new BeanHbinImportMapping(1, 'c', true); 
     return bean; 
    } 
} 

的SQL測試工作。

感謝。

Answer 1

您正在傳遞參數（在本例中爲null），並且查詢沒有任何查詢參數...可以向查詢添加參數或從方法調用中刪除參數。

** **的RowMapper

• 使用此接口映射每一行結果對象的優點。 mapRow（）此方法不應該在ResultSet上調用next（）;它只能映射當前行的值。並返回對象列表。*

applicationConttext.xml

<bean id="dataSource" class="org.apache.commons.dbcp.BasicDataSource"> 
     <property name="driverClassName" value="com.mysql.jdbc.Driver" /> 
     <property name="url" value="jdbc:mysql://localhost:3306/yash" /> 
     <property name="username" value="root" /> 
     <property name="password" value="" /> 
    </bean> 

    <bean id="jt" class="org.springframework.jdbc.core.JdbcTemplate"> 
     <property name="dataSource" ref="dataSource" /> 
    </bean> 
<bean id="empdao" class="gmail.daos.EmpDao"> 
     <property name="jt" ref="jt"/> 
</bean> 

• DAO類*

  public class EmpDao { 
      private JdbcTemplate jt; 
  public List<EmpDto> listEmpoyees(){ 
  String sql = "select * FROM emp"; 
      List<EmpDto> emplist = jt.query(sql, new RowMapper() { 
  
         public EmpDto mapRow(ResultSet rs, int rowNum) throws SQLException { 
          EmpDto emp = new EmpDto(); 
  
          emp.setId(rs.getInt("id")); 
          emp.setName(rs.getString("name")); 
          emp.setAge(rs.getInt("age")); 
          emp.setSalary(rs.getInt("salary")); 
          emp.setAddress(rs.getString("address")); 
  
          System.out.println("***"); 
  
          return emp; 
         } 
  
        });  
        return emplist; 
  }} 
  

如果你用這種方式他們會沒有ReselutSetExecption。
