|
||||
worldwide, non-exclusive, no-charge, royalty-free, irrevocable
|
||||
copyright license to reproduce, prepare Derivative Works of,

or contributory patent infringement, then any patent licenses
|
||||
granted to You under this License for that Work shall terminate
|
||||
as of the date such litigation is filed.
|
||||
|
||||
4. Redistribution. You may reproduce and distribute copies of the
|
||||
Work or Derivative Works thereof in any medium, with or without
|
||||
modifications, and in Source or Object form, provided that You

||||
|
||||
(a) You must give any other recipients of the Work or
|
||||
Derivative Works a copy of this License; and
|
||||
|
||||
(b) You must cause any modified files to carry prominent notices
|
||||
stating that You changed the files; and
|
||||
|
||||
(c) You must retain, in the Source form of any Derivative Works
|
||||
that You distribute, all copyright, patent, trademark, and
|
||||
attribution notices from the Source form of the Work,
|
||||
excluding those notices that do not pertain to any part of
|
||||
the Derivative Works; and
|
||||
|
||||
(d) If the Work includes a "NOTICE" text file as part of its
|
||||
distribution, then any Derivative Works that You distribute must
|
||||
include a readable copy of the attribution notices contained
|
||||
within such NOTICE file, excluding those notices that do not
|
||||
pertain to any part of the Derivative Works, in at least one
|
||||
of the following places: within a NOTICE text file distributed
|
||||
as part of the Derivative Works; within the Source form or
|
||||
documentation, if provided along with the Derivative Works; or,
|
||||
within a display generated by the Derivative Works, if and
|
||||
wherever such third-party notices normally appear. The contents
|
||||
of the NOTICE file are for informational purposes only and
|
||||
do not modify the License. You may add Your own attribution
|
||||
notices within Derivative Works that You distribute, alongside
|
||||
or as an addendum to the NOTICE text from the Work, provided
|
||||
that such additional attribution notices cannot be construed
|
||||
as modifying the License.
|
||||
|
||||
You may add Your own copyright statement to Your modifications and
|
||||
may provide additional or different license terms and conditions
|
||||
for use, reproduction, or distribution of Your modifications, or
|
||||
for any such Derivative Works as a whole, provided Your use,
|
||||
reproduction, and distribution of the Work otherwise complies with
|
||||
the conditions stated in this License.
|
||||
|
||||
5. Submission of Contributions. Unless You explicitly state otherwise,
|
||||
any Contribution intentionally submitted for inclusion in the Work
|
||||
by You to the Licensor shall be under the terms and conditions of
|
||||
this License, without any additional terms or conditions.
|
||||
Notwithstanding the above, nothing herein shall supersede or modify
|
||||
the terms of any separate license agreement you may have executed
|
||||
with Licensor regarding such Contributions.
|
||||
|
||||
6. Trademarks. This License does not grant permission to use the trade
|
||||
names, trademarks, service marks, or product names of the Licensor,
|
||||
except as required for reasonable and customary use in describing the
|
||||
origin of the Work and reproducing the content of the NOTICE file.
|
||||
|
||||
7. Disclaimer of Warranty. Unless required by applicable law or
|
||||
agreed to in writing, Licensor provides the Work (and each
|
||||
Contributor provides its Contributions) on an "AS IS" BASIS,
|
||||
WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
|
||||
implied, including, without limitation, any warranties or conditions
|
||||
of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
|
||||
PARTICULAR PURPOSE. You are solely responsible for determining the
|
||||
appropriateness of using or redistributing the Work and assume any
|
||||
risks associated with Your exercise of permissions under this License.
|
||||
|
||||
8. Limitation of Liability. In no event and under no legal theory,
|
||||
whether in tort (including negligence), contract, or otherwise,
|
||||
unless required by applicable law (such as deliberate and grossly
|
||||
negligent acts) or agreed to in writing, shall any Contributor be
|
||||
liable to You for damages, including any direct, indirect, special,
|
||||
incidental, or consequential damages of any character arising as a
|
||||
result of this License or out of the use or inability to use the
|
||||
Work (including but not limited to damages for loss of goodwill,
|
||||
work stoppage, computer failure or malfunction, or any and all
|
||||
other commercial damages or losses), even if such Contributor
|
||||
has been advised of the possibility of such damages.
|
||||
|
||||
9. Accepting Warranty or Additional Liability. While redistributing
|
||||
the Work or Derivative Works thereof, You may choose to offer,
|
||||
and charge a fee for, acceptance of support, warranty, indemnity,
|
||||
or other liability obligations and/or rights consistent with this
|
||||
License. However, in accepting such obligations, You may act only
|
||||
on Your own behalf and on Your sole responsibility, not on behalf
|
||||
of any other Contributor, and only if You agree to indemnify,
|
||||
defend, and hold each Contributor harmless for any liability
|
||||
incurred by, or claims asserted against, such Contributor by reason
|
||||
of your accepting any such warranty or additional liability.
|
||||
|
||||
END OF TERMS AND CONDITIONS
|
||||
|
||||

# SimpleJDBC
|
||||
|
||||
对 JDBC 的简单封装。
|
||||
|
||||
之前遇到的一个老项目,没有引入任何 ORM 框架,对数据库的操作几乎都在写原生 JDBC。故自己写了几个工具类,对 JDBC 进行简单封装。
|
||||
|
||||
## 查询
|
||||
|
||||
### 查询方法
|
||||
|
||||
- `query`:**最基础的查询方法**。可使用 `ResultHandler` 将查询结果映射为 Java 对象。
|
||||
- `queryList`:**查询列表**。可使用 `RowMapper` 将结果的每一行数据映射为 Java 对象,返回列表。
|
||||
- `queryFirst`:**查询,并获取第一行数据**。一般可以结合 `LIMIT 1` 使用。可使用 `RowMapper` 将结果的第一行数据映射为 Java 对象,返回 `Optional`。
|
||||
- `queryFirstXXX`:**查询,并获取第一行数据的第一个字段**,并转换为对应类型,返回对应的类型的 `Optional`。
|
||||
- `queryAsBoolean`:**查询,并获取第一行数据的第一个字段**,并转换为布尔类型。如果结果为空,则返回 `false`。
|
||||
|
||||
### 结果映射
|
||||
|
||||
- `ResultHandler` 用于处理查询结果,自定义逻辑将完整的 `ResultSet` 映射为 Java 对象。 *结果可以是任意类型(包括集合)。*
|
||||
- `RowMapper` 用于将 `ResultSet` 中的一行数据映射为 Java 对象。
|
||||
- `RowMapper#HASH_MAP_MAPPER`:将 `ResultSet` 中的一行数据映射为 `HashMap`。
|
||||
- `RowMapper#beanRowMapper`:返回将 `ResultSet` 转换为 Java Bean 的默认实现。
|
||||
|
||||
## 更新
|
||||
|
||||
- `int update`:**执行 DML**,包括 `INSERT`、`UPDATE`、`DELETE` 等。返回受影响行数。
|
||||
- `<T> List<T> update`:**执行 DML**,自动生成的字段将使用 `rowMapper` 进行映射,并返回列表。
|
||||
- `List<int[]> batchUpdate`:**分批次执行 DML**,返回每个批次的每条 SQL 语句影响的行数。
|
||||
- `List<int[]> batchUpdateAndIgnoreException`:**分批次执行 DML,如果某个批次出现异常,继续执行下一个批次**。返回每个批次的每条 SQL 语句影响的行数。
|
||||
|
||||
## 事务
|
||||
|
||||
- `executeTransaction`:**执行事务**。传入一个 `ThrowingConsumer` 函数,入参是一个 `JdbcExecutor` 对象,在 `ThrowingConsumer` 内使用该入参执行 jdbc 操作。如果 `ThrowingConsumer` 内部有异常抛出,这些操作将被回滚。
|
||||
|
||||
- `commitIfTrue`:**执行事务**。传入一个 `ThrowingPredicate` 函数,入参是一个 `JdbcExecutor` 对象,在 `ThrowingPredicate` 内使用该入参执行 jdbc 操作。如果`ThrowingPredicate` 返回 `true`,则提交事务;如果返回 `false` 或有异常抛出,则回滚这些操作。
|
||||
|
||||
## 参数构建
|
||||
|
||||
此项目中的所有查询和更新的方法,都**不使用可变长入参**,避免强行将 SQL 语句的参数列表放在最后,也避免和数组发生歧义。
|
||||
|
||||
### 构建参数列表
|
||||
|
||||
可使用 `ParamBuilder#buildParams` 构建 `Object[]` 数组作为 SQL 的参数列表。该方法会自动将 `Optional` 中的值“拆”出来。
|
||||
|
||||
### 批量构建参数列表
|
||||
|
||||
使用 `ParamBuilder#buildBatchParams`,将使用传入的函数,将集合中的每一个元素转为 `Object[]`,并返回一个 `List<Object[]>`。
|
||||
|
||||
## 示例
|
||||
|
||||
创建 SimpleJdbcTemplate 对象
|
||||
```java
|
||||
SimpleJdbcTemplate jdbcTemplate = new SimpleJdbcTemplate(dataSource);
|
||||
```
|
||||
|
||||
查询
|
||||
```java
|
||||
// 查询
|
||||
List<Account> list = jdbcTemplate.query(
|
||||
"SELECT * FROM account WHERE deleted = 0 AND username LIKE ? AND org_no = ?",
|
||||
buildParams("admin%", "0000"),
|
||||
rs -> {
|
||||
List<T> result = new ArrayList<>();
|
||||
while (rs.next()) {
|
||||
result.add(new Account(
|
||||
rs.getLong("id"),
|
||||
rs.getString("username"),
|
||||
rs.getString("password"),
|
||||
rs.getString("org_no"),
|
||||
rs.getTimestamp("create_time"),
|
||||
rs.getTimestamp("update_time")
|
||||
));
|
||||
}
|
||||
return result;
|
||||
}
|
||||
);
|
||||
|
||||
// 查询列表
|
||||
List<Account> list = jdbcTemplate.queryList(
|
||||
"SELECT * FROM account WHERE deleted = 0 AND username LIKE ? AND org_no = ?",
|
||||
buildParams("admin%", "0000"),
|
||||
(rs, rowNum) -> new Account(
|
||||
rs.getLong("id"),
|
||||
rs.getString("username"),
|
||||
rs.getString("password"),
|
||||
rs.getString("org_no"),
|
||||
rs.getTimestamp("create_time"),
|
||||
rs.getTimestamp("update_time")
|
||||
)
|
||||
);
|
||||
|
||||
// 查询一行数据
|
||||
Optional<Account> account = jdbcTemplate.queryFirst(
|
||||
"SELECT * FROM account WHERE deleted = 0 AND id = ?",
|
||||
buildParams(10000L),
|
||||
(rs, rowNum) -> new Account(
|
||||
rs.getLong("id"),
|
||||
rs.getString("username"),
|
||||
rs.getString("password"),
|
||||
rs.getString("org_no"),
|
||||
rs.getTimestamp("create_time"),
|
||||
)
|
||||
)
|
||||
|
||||
// 查询一行数据,并获取第一个字段
|
||||
OptionalInt age = jdbcTemplate.queryFirstInt(
|
||||
"SELECT age FROM view_account WHERE deleted = 0 AND id = ?",
|
||||
buildParams(10000L)
|
||||
);
|
||||
|
||||
// 查询 boolean
|
||||
boolean exists = jdbcTemplate.queryAsBoolean(
|
||||
"SELECT EXISTS(SELECT 1 FROM account WHERE deleted = 0 AND id = ? LIMIT 1)",
|
||||
buildParams(10000L)
|
||||
);
|
||||
```
|
||||
|
||||
更新
|
||||
```java
|
||||
// 执行 DML
|
||||
int affectedRows = jdbcTemplate.update(
|
||||
"UPDATE account SET deleted = 1 WHERE id = ?",
|
||||
buildParams(10000L)
|
||||
);
|
||||
|
||||
// 执行 DML,并获取生成的主键
|
||||
List<Pair<Long, LocalDateTime>> keys = jdbcTemplate.update(
|
||||
"INSERT INTO account (username, password, org_no) VALUES (?, ?, ?)",
|
||||
buildParams("admin", "123456", "0000"),
|
||||
(rs, rowNum) -> Pair.of(
|
||||
rs.getLong("id"),
|
||||
rs.getObject("create_time", LocalDateTime.class)
|
||||
)
