Java JDBC MySQL插入类型时间戳失败

我无法正确插入时间戳字段

方法如下所示：

private static void addPickup(Connection conn, boolean debug, String 
        logfileName, String serverName, String mapName, long start, 
        long end) throws SQLException {

    try (CallableStatement statement = conn.prepareCall("{CALL AddPickup "
                 + "(?, ?, ?, ?, ?) }")) {
        statement.setString(1, logfileName);
        statement.setString(2, serverName);
        statement.setString(3, mapName);
        statement.setTimestamp(4, new Timestamp(start));
        statement.setTimestamp(5, new Timestamp(end));
        statement.execute();
    }
}

start的值为1373573918000

end的值为1373574819000

程序：

CREATE PROCEDURE AddPickup(
    IN logfilename VARCHAR(45), 
    IN servername VARCHAR(10), 
    IN mapname VARCHAR(20),
    IN start TIMESTAMP,
    IN end TIMESTAMP
)
AddPickup:BEGIN
IF EXISTS(SELECT p.id FROM pickup p WHERE p.logfile_name = logfilename) THEN
    LEAVE AddPickup;
END IF;

INSERT IGNORE INTO map (name) VALUES (mapname);
INSERT IGNORE INTO server (name) VALUES (servername);
INSERT INTO pickup (logfile_name, server_id, map_id, started, ended, datetime) 
    VALUES (
        logfilename, 
        (SELECT s.id FROM server s WHERE s.name = servername),
        (SELECT m.id FROM map m WHERE m.name = mapname),
        start,
        end,
        NOW()
    );
END //

CREATE TABLE map (
    id INT UNSIGNED AUTO_INCREMENT PRIMARY KEY,
    name VARCHAR(20) UNIQUE NOT NULL
) ENGINE = 'InnoDB';

CREATE TABLE server (
    id INT UNSIGNED AUTO_INCREMENT PRIMARY KEY,
    name VARCHAR(10) UNIQUE NOT NULL
) ENGINE = 'InnoDB';

CREATE TABLE pickup (
    id INT UNSIGNED AUTO_INCREMENT PRIMARY KEY,
    logfile_name VARCHAR(45) UNIQUE NOT NULL,
    server_id INT UNSIGNED NOT NULL,
    map_id INT UNSIGNED NOT NULL,
    started TIMESTAMP NOT NULL,
    ended TIMESTAMP NOT NULL,
    datetime DATETIME NOT NULL,
    FOREIGN KEY (map_id) REFERENCES map(id) ON UPDATE CASCADE ON DELETE CASCADE,
    FOREIGN KEY (server_id) REFERENCES server(id) ON UPDATE CASCADE ON DELETE CASCADE
 ) ENGINE = 'InnoDB';

表格：

CREATE PROCEDURE AddPickup(
    IN logfilename VARCHAR(45), 
    IN servername VARCHAR(10), 
    IN mapname VARCHAR(20),
    IN start TIMESTAMP,
    IN end TIMESTAMP
)
AddPickup:BEGIN
IF EXISTS(SELECT p.id FROM pickup p WHERE p.logfile_name = logfilename) THEN
    LEAVE AddPickup;
END IF;

INSERT IGNORE INTO map (name) VALUES (mapname);
INSERT IGNORE INTO server (name) VALUES (servername);
INSERT INTO pickup (logfile_name, server_id, map_id, started, ended, datetime) 
    VALUES (
        logfilename, 
        (SELECT s.id FROM server s WHERE s.name = servername),
        (SELECT m.id FROM map m WHERE m.name = mapname),
        start,
        end,
        NOW()
    );
END //

CREATE TABLE map (
    id INT UNSIGNED AUTO_INCREMENT PRIMARY KEY,
    name VARCHAR(20) UNIQUE NOT NULL
) ENGINE = 'InnoDB';

CREATE TABLE server (
    id INT UNSIGNED AUTO_INCREMENT PRIMARY KEY,
    name VARCHAR(10) UNIQUE NOT NULL
) ENGINE = 'InnoDB';

CREATE TABLE pickup (
    id INT UNSIGNED AUTO_INCREMENT PRIMARY KEY,
    logfile_name VARCHAR(45) UNIQUE NOT NULL,
    server_id INT UNSIGNED NOT NULL,
    map_id INT UNSIGNED NOT NULL,
    started TIMESTAMP NOT NULL,
    ended TIMESTAMP NOT NULL,
    datetime DATETIME NOT NULL,
    FOREIGN KEY (map_id) REFERENCES map(id) ON UPDATE CASCADE ON DELETE CASCADE,
    FOREIGN KEY (server_id) REFERENCES server(id) ON UPDATE CASCADE ON DELETE CASCADE
 ) ENGINE = 'InnoDB';

它将所有内容插入表中，只插入时间戳字段、拾取开始和拾取结束始终显示“0000-00-00:00:00”，我不知道为什么。

我认为问题在于您传递给设置时间戳的参数中

当我使用setTimestamp时，如果我没有使用特定的日期，我总是将new date（）.getTime（）作为参数传递

private static void addPickup(Connection conn, boolean debug, String 
    logfileName, String serverName, String mapName, long start, 
    long end) throws SQLException {

try (CallableStatement statement = conn.prepareCall("{CALL AddPickup "
             + "(?, ?, ?, ?, ?) }")) {
    statement.setString(1, logfileName);
    statement.setString(2, serverName);
    statement.setString(3, mapName);
    statement.setTimestamp(4, new Date().getTime());
    statement.setTimestamp(5, new Date().getTime());
    statement.execute();
}

}

我不太清楚它在MYSQL中是如何工作的，但当我在SQLSERVER中使用时间戳时，每当创建行时，都会自动生成时间戳，在这种情况下，我没有从查询中为时间戳提供任何值。因此，只需尝试插入其他值 希望它也能帮助你
