Question

我使用NamedParameterJdbcTemplate将参数传递给Query。但我得到跟踪细节作为一个警告和参数绑定没有显示。主要问题是它是显示执行sql但我想参数也只是它的一部分？（问号）来了。警告绑定发生后执行是好的但是在日志中看不到绑定。请帮我检查一下。

列索引1，参数值[mike]，值类 [java.lang.String]，SQL类型未知列索引2，参数值 [1]，值类[java.lang.Integer]，SQL类型未知

存储库：

@Repository
public class DataRepository {
    private static Logger log = LoggerFactory.getLogger(DataRepository.class);

    @Autowired
    private NamedParameterJdbcTemplate jdbcTemplate;

    public Data findDataObjet() throws Exception {

        Map<String, Object> parameters = new HashMap<>();
        parameters.put("id1", "mike");
        parameters.put("id2", new Long(1));

        String sqlString = "select * from table1 where id1 = ":id1" and id2 = :id2";

        Data extObj = jdbcTemplate.query(sqlString, parameters, (rs) -> {
            if (rs != null && rs.next()) {
                Data innerObj = new Data();
                innerObj.setName(rs.getString("name"));             
                return innerObj;
            } else {
                log.info("No records found:"+rs);
                return null;
            }
        });

        return extObj;

    }
}

application.properties：

spring.datasource.url=url
spring.datasource.username=user
spring.datasource.password=password
spring.datasource.driver-class-name=com.microsoft.sqlserver.jdbc.SQLServerDriver

spring.datasource.type = com.zaxxer.hikari.HikariDataSource
spring.datasource.hikari.connection-timeout=60000
spring.datasource.hikari.maximum-pool-size=2

Answer 1

使用Wrapper类SqlParameterValue，通知将消失：

    Map<String, Object> parameters = new HashMap<>();
    parameters.put("id1", new SqlParameterValue(Types.VARCHAR,"mike"));
    parameters.put("id2", new SqlParameterValue(Types.BIGINT,new Long(1)));

在日志文件中，您将看到SQL类型91 ...，而不是未知的SQL类型

设置SQL语句参数值：列索引1，参数值[名称]，值类[java.lang.String]，SQL类型未知
