软件介绍
jDBI 提供一个 Java 简单操作接口, 它不是一个抽象层而是一个类库是的公共的操作更简单、还有能力去做一些更复杂的操作。
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
// 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
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();
