Java 简单操作接口 JDBI
JDBI 是 Java 的 SQL 便捷操作库，尝试使用集合，beans 等等来暴露 Java 中的关系型数据库，可以维护相同级别的 JDBC。提供两个不同样式的 APIs：fluent 和 sql object。
Fluent API
|
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 |
Java代码 // using in-memory H2 database DataSource ds = JdbcConnectionPool.create("jdbc:h2:mem:test", "username", "password"); DBI dbi = new DBI(ds); Handle h = dbi.open(); h.execute("create table something (id int primary key, name varchar(100))"); h.execute("insert into something (id, name) values (?, ?)", 1, "Brian"); String name = h.createQuery("select name from something where id = :id") .bind("id", 1) .map(StringMapper.FIRST) .first(); assertThat(name, equalTo("Brian")); h.close(); |
SQL Object API
|
1 2 3 4 5 6 7 8 9 10 11 12 13 14 |
Java代码 public interface MyDAO { @SqlUpdate("create table something (id int primary key, name varchar(100))") void createSomethingTable(); @SqlUpdate("insert into something (id, name) values (:id, :name)") void insert(@Bind("id") int id, @Bind("name") String name); @SqlQuery("select name from something where id = :id") String findNameById(@Bind("id") int id); /** * close with no args is used to close the connection */ void close(); } |
