Mysql 获取我刚刚用Spring插入的主键

我在MySQL的表中插入一行。代码如下：

public final String SQLADDPROJECT="insert into table(value1,value2,value3) values(?,?,?)";
getJdbcTemplate().update(SQLADDPROJECT, new Object[]{model.getValue1, 
            model.getValue2(),
            model.getValue3()});

此insert语句工作正常，模型不为空。该表有一个主键是自动递增的，我希望获得该键，以便稍后在代码中使用它。我做了一些搜索，使用了一个钥匙夹，这样：

KeyHolder keyHolder = new GeneratedKeyHolder();
public final String SQLADDPROJECT="insert into table(value1,value2,value3) values(?,?,?)";
getJdbcTemplate().update(SQLADDPROJECT, new Object[]{model.getValue1, 
            model.getValue2(),
            model.getValue3()}, keyHolder);
Long pk=keyHolder.getKey().longValue();

但我收到一个例外：

我可以这样使用钥匙夹吗？如果没有，我如何获得刚刚插入的pk？多谢各位

---

注意：我的类扩展了JdbcDaoSupport

，因为在

jdbcdemplate

中没有带

update（String sql，Object[]args，KeyHolder generatedKeyHolder）

参数的方法

您只有

更新（PreparedStatementCreator psc，KeyHolder generatedKeyHolder）

---

您的方法调用正在调用一个重载方法

update（字符串sql、对象[]args、int[]argTypes）

这导致了

java.sql.SQLException:无效参数值：

我已经看到了他们使用

键盘夹的例子，但我发现当有一个更简单的方法可用时太麻烦了。我今天早上确实做了。您使用一个
SimpleJdbcInsert
对象，它将返回生成的密钥

SimpleJdbcInsert insertContactList = new SimpleJdbcInsert(jdbcTemplate)
            .withTableName("FOO_TABLE").usingColumns("Other", "Columns")
            .usingGeneratedKeyColumns("FooID");

Map<String,Object> insertParameters = new HashMap<String, Object>();
/* 
 * These key pair values must match the columns that you 
 * specified in the .usingColumns() call above. If you don't
 * want to insert any other data, just don't call the .usingColumns method,
 * and insert a blank map.
 */ 
insertParameters.put("Other", foo.getOther());
insertParameters.put("Columns", foo.getColumns());

Number generatedFooId = insertContactList.executeAndReturnKey(insertParameters);
return generatedFooId;

SimpleJDBCInsertContactList=new SimpleJDBCCinsert（jdbcTemplate）
.withTableName（“FOO_TABLE”）。使用列（“其他”、“列”）
.使用GeneratedKeyColumns（“FooID”）；
Map insertParameters=new HashMap（）；
/* 
*这些密钥对值必须与您选择的列匹配
*在上面的.usingColumns（）调用中指定。如果你不
*要插入任何其他数据，请不要调用.usingColumns方法，
*并插入一张空白地图。
*/ 
insertParameters.put（“其他”，foo.getOther（））；
insertParameters.put（“Columns”，foo.getColumns（））；
Number generatedFooId=insertContactList.executeAndReturnKey（insertParameters）；
返回生成的fooid；

这个方法显然是假设您有一个可用的
JdbcTemplate
，并且您的PK是数据库生成的值

如果其中任何一个不清楚，请告诉我，我可以扩展我的答案。
我知道，但有一个带有签名更新的方法（字符串sql、对象…args），这意味着您可以向该方法添加任意数量的任何类型的参数。我原以为添加钥匙夹可以奏效，但实际上不行。我正在尝试，当我看到它是否奏效时，我会给你反馈。谢谢干得不错，谢谢！如果有人使用此答案，并且在其数据库中有任何“二进制”字段，并将其用作“true”或“false”，如果您执行“insertparameters.put”（“其他”，true）；它将启动DataTruncationException。您必须执行“insertparameters.put”（“其他”，1）”
