Question

我使用spring将批记录插入数据库。但我收到此错误：java.sql.SQLException：无法在java.util.ArrayList和JAVA_OBJECT之间进行转换。能帮助我做错了吗

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：

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);

或当我只通过一个工作时。

请帮助：）

Answer 1

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);

sprint namedParameterJdbcTemplate batchUpdate with in
