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正在测试工作。

感谢。

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...要么向查询添加参数，要么从方法调用中删除参数。

** RowMapper **

使用此接口的优点是将每一行映射到结果对象。 mapRow（）此方法不应调用ResultSet上的next（）;它只应映射当前行的值。并返回对象列表。*

applicationConttext.xml

    case class Foo(x: Int)
    case class Bar(x: Double)

    val a = Foo(5)
    val b = Bar(5)

    a.x == b.x //res4: Boolean = true
    a == b //res5: Boolean = false

DAO Class *

<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>

如果您使用这种方式，他们就不会有ReselutSetExecption。
