Question

我在我的spring应用程序中使用MS-SQL服务器。我有一个商店程序，我想从我的应用程序执行。

CREATE PROCEDURE dbo.spCheckPerson (
    @inXML XML,
    @outXML XML OUTPUT,
    @inDebug BIT = 0 ) 
AS
    --do sth

SET @outXML = '<person><name>Piotr</name></person>'

RETURN 0

我尝试通过这个DAO执行它：

import java.sql.SQLException;
import java.sql.SQLXML;
import java.sql.Types;
import java.util.Map;

import javax.sql.DataSource;

import org.springframework.jdbc.core.JdbcTemplate;
import org.springframework.jdbc.core.SqlOutParameter;
import org.springframework.jdbc.core.SqlParameter;
import org.springframework.jdbc.core.simple.SimpleJdbcCall;
import org.springframework.jdbc.support.xml.Jdbc4SqlXmlHandler;

public class PersonDAOImpl implements PersonDAO {

    private JdbcTemplate jdbcTemplate;
    private SimpleJdbcCall spCheckPerson;

    public PersonDAOImpl(DataSource dataSource) {
        jdbcTemplate = new JdbcTemplate(dataSource);
    }

    @Override
    public String checkPersonData(String personData) {
        Jdbc4SqlXmlHandler sqlXmlHandler = new Jdbc4SqlXmlHandler();
        spCheckPerson = new SimpleJdbcCall(jdbcTemplate)
                .withoutProcedureColumnMetaDataAccess()
                .withProcedureName("spCheckPerson")
                .declareParameters(new SqlParameter("inXML", Types.SQLXML))
                .declareParameters(new SqlOutParameter("outXML", Types.SQLXML));
        Map<String, Object> result = spCheckPerson.execute(sqlXmlHandler.newSqlXmlValue("<test>Test</test>"));
        return ((SQLXML) result.get("outXML")).getString();
    }

}

，但我收到错误：

我该如何正确接收这个物体？我应该使用哪个类来施展价值？什么是TDS协议？我尝试使用SQLXML中的方法：getCharacterStream（），但它给出了相同的异常。

如何使用spring jdbcTemplate从storedProcedudure接收XML参数？
