Spring JDBCTemplate 给出 InvalidResultSetAccessException 无效的列索引

Question

我使用 Spring 的 SimpleJDBCTemplate 来访问 Oracle DB。这是我的代码。

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

行映射器是：

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;
    }
}

sql 已测试工作正常。

谢谢。

Answer 1

您正在传递参数（在本例中为 null），并且查询没有任何查询参数...向查询添加参数或从方法调用中删除参数。

Answer 2

** RowMapper**

• 使用此接口的优点是将每一行映射到一个结果对象。 mapRow() 该方法不应在 ResultSet 上调用 next()；它只应该映射当前行的值。并返回对象列表。*

applicationContext.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 类 *

  公共类 EmpDao {
      私有 JdbcTemplate jt；
  公共列表列出员工（）{
   字符串sql =“选择* FROM emp”;
    列表 emplist = jt.query(sql, new RowMapper() {
  
                  公共 EmpDto mapRow(ResultSet rs, int rowNum) 抛出 SQLException {
                      EmpDto emp = new EmpDto();
  
                      emp.setId(rs.getInt("id"));
                      emp.setName(rs.getString("name"));
                      emp.setAge(rs.getInt("年龄"));
                      emp.setSalary(rs.getInt("工资"));
                      emp.setAddress(rs.getString("地址"));
  
                      System.out.println("***");
  
                      返回雇员；
                  }
  
              });      
              返回雇佣列表；
  }}
  

如果您使用这种方式，它们将不会出现 ReselutSetExecption。
