## eorm-spring

这是一个基于Spring `JdbcTemplate` 和 `NamedParameterJdbcTemplate` 的ORM框架。

Ta的前身是[dbhelper](https://github.com/deng-hb/dbhelper)，项目需要`spring 3.x`以上版本，还依赖项目[multi-line](https://github.com/deng-hb/multi-line)一个Java多行文本支持类。

### Maven依赖

```xml

    com.denghb

    eorm-spring

    1.1.2

```

### 配置

```java

@Autowired

private JdbcTemplate jdbcTemplate;

@Bean

public Eorm eorm() {

    return new EormMySQLImpl(jdbcTemplate);

}

```

### 基本操作

```java

@Autowired

private Eorm db;

伪代码{

    // 执行一条SQL

    int r = db.execute(String sql, Object... args);

    

    // 执行一条SQL查询

    List list = db.select(Class clazz, String sql, Object... args);

    

    // 插入一个对象

    db.insert(T domain);

    

    // 修改一个对象

    db.update(T domain);

    

    // 删除一个对象

    db.delete(T domain);

    

    

    // 按主键删除

    db.delete(Class clazz, Object... ids);

    

    // 查询返回一个对象

    T db.selectOne(Class clazz, String sql, Object... args);

    

    // 按主键查询一条记录

    T db.selectByPrimaryKey(Class clazz, Object... args);

}

```

### 模版SQL

```

SQL 片段1

#if (表达式)

  SQL 片段2

#elseIf (表达式)

  SQL 片段3

#else

  SQL 片段4

#end

SQL 片段5

```

#### 模版SQL示例

```java

String sql = ""/*{

    select count(*) from tb_user u where u.deleted = 0

    #if (null != #nickName)

        and u.nick_name like concat('%', :nickName, '%')

    #elseIf (null != #openId)

        and u.openId = :openId

    #end 

}*/;

Integer count = db.selectOne(Integer.class, sql, new HashMap() {{

    put("nickName", "张三");

}});

System.out.println(count);

```

### Java Entity 生成工具

Idea IDE下载[Eorm](https://plugins.jetbrains.com/plugin/12618-eorm)插件，项目开源地址[eorm-idea-plugin](https://github.com/deng-hb/eorm-idea-plugin)

![Eorm Entity Generator](./eorm-idea-plugin.png)

下载后打开方式

```

Menu > Code > Eorm Entity Generator

```

Eorm还提供多行SQL语法高亮，SQL提示
