我正在使用spring将批处理记录插入数据库。但是我收到此错误:java.sql.SQLException:无法在java.util.ArrayList和JAVA_OBJECT之间进行转换。
你能帮我做错什么吗
private static final String INSERT_BATCH_QUERY ="INSERT INTO TEST_TABLE (ID,TEST_ID) select :id, substring((SELECT ', ' + USERS.COMMON_NAME FROM USERS WHERE USERS.ID IN ( :testIds ) FOR XML PATH('')), 2, 4000);
public class Test{
private int id;
private List<Intenger> testIds;
//**getters and setters**//
}
public static void Main(String... args){
List<Test> myTe=new ....
SqlParameterSource[] sqlParameterSource = SqlParameterSourceUtils.createBatch(myTe.toArray());
result = namedParameterJdbcTemplate.batchUpdate(INSERT_BATCH_QUERY, sqlParameterSource);
}
错误:
Caused by: java.sql.SQLException: Unable to convert between java.util.ArrayList and JAVA_OBJECT.

如果我使用硬编码值:
private static final String INSERT_BATCH_QUERY ="INSERT INTO TEST_TABLE (ID,TEST_ID) select :id, substring((SELECT ', ' + USERS.COMMON_NAME FROM USERS WHERE USERS.ID IN ( 1234,654,55 ) FOR XML PATH('')), 2, 4000);
或者当我仅通过一个int时,它就起作用了。
请帮忙 :)
最佳答案
使用SqlParameterSource定义参数,以便查询将替换占位符SqlParameterSource params = new MapSqlParameterSource("testIds", testIds).addValue("id", id);
