== 简介

Mybatis、通用mapper、Jpa的Base Service，实现了基本的CRUD。

== 1. 依赖

=== 1.1 *Gradle工程*
[source, groovy]
----
repositories {

    ...
    maven { url "https://raw.githubusercontent.com/jgaybjone/mvnrepo/master" }
    mavenCentral()
}

dependencies {
	//下面根据情况三选一
	compile 'cn.jgayb:mybatis-service:1.0-RELEASE' //mybatis项目使用
	compile 'cn.jgayb:tk-mybatis-service:1.0-RELEASE' //通用mapper项目使用
	compile 'cn.jgayb:jpa-service:1.0-RELEASE' //spring data jpa项目使用
}

----
=== 1.2 *Maven工程*
[source, xml]

== 2. Mybatis BaseService使用介绍

=== 2.1 *自己的Mapper继承IMapper接口*
[source, java]
----
public interface UserMapper extends IMapper<User> {

	User selectById(String id);

	void update(User user);

}
----

=== 2.2 *自己的Service继承BaseService*
[source,java]
----

public interface UserService extends BaseService<User> {

}

----

=== 2.3 *实现类*
[source,java]
----
@Service
public class UserServiceImpl implements UserService{

    @Autowird
    private UserMapper userMapper;

    @Override
    public UserMapper getMapper(){
        return this.userMapper;
    }

    @Override
    @Transactional
    public void crudAndConsumer(Consumer<UserMapper> consumer){
        consumer.accept(userMapper);
    }

    ...

}
----

=== 2.4 *方法调用例子*
[source,java]
----
public class example{

    @Autowird
    private UserService userService;

    //Lambda 函数式优雅使用
	public void findAndDeletedById(String id){
	    userService.crudAndConsumer(userMapper -> {
	        User user = userMapper.selectById(id);
	        user.setDisable(true);
	        userMapper.updateBySelective(user);
	    });
	}
}
----

== 3. 通用mapper BaseService使用介绍

=== 3.1 所有的mapper都继承BaseMapper
[source,java]
----
public interface UserMapper extends BaseMapper<User> {

	/**
	*  通用mapper已经很有很多方法了
	*/
	UserDto selectById(String id);

}
----
=== 3.2 *自己的Service继承BaseService*
[source,java]
----

public interface UserService extends BaseService<User> {

}

----

=== 3.3 *实现类*
[source,java]
----
@Service
public class UserServiceImpl implements UserService{

    @Autowird
    private UserMapper userMapper;

    @Override
    public UserMapper getMapper(){
        return this.userMapper;
    }

    @Override
    @Transactional
    public void crudAndConsumer(Consumer<UserMapper> consumer){
        consumer.accept(userMapper);
    }

    ...

}
----

=== 3.4 *方法调用例子*
[source,java]
----
public class example{

    @Autowird
    private UserService userService;

    //Lambda 函数式优雅使用
	public void findAndDeletedById(String id){
	    userService.crudAndConsumer(userMapper -> {
	        UserDto userDto = userMapper.selectById(id);
	        userDto.setDisable(true);
	        userMapper.updateBySelective(userDto);
	    });
	}
}

== 4. Spring data jpa BaseService介绍

=== 4.1 *自己的Service继承BaseService*
[source,java]
----

public interface UserService extends BaseService<User> {

}

----

=== 4.2 *Service的实现*
[source,java]
----
@Service
public class UserServiceImpl implements UserService{

    @Autowird
    private UserRepository userRepository;

    @Override
    public UserRepository getRepository(){
        return this.userRepository;
    }

    @Override
    @Transactional
    public void crudAndConsumer(Consumer<UserRepository> consumer){
        consumer.accept(userRepository);
    }

    ...

}
----

=== 4.3 *方法调用例子*
[source,java]
----
public class example{

    @Autowird
    private UserService userService;

    //Lambda 函数式优雅使用
	public void findAndDeletedById(String id){
	    userService.crudAndConsumer(userRepository -> {
	        User user = userRepository.findById(id);
	        //CRUD
	        ...

	        userRepository.save(user);
	    });
	}
}
