Easy Mapper Processor

--- 一个基于MyBatis的注解扩展 ---

目前支持的功能

• JSON字段映射，自动生成JSON字段TypeHandler。

使用手册

配置依赖

    <dependency>
        <groupId>com.iakuil</groupId>
        <artifactId>ez-mapper-processor</artifactId>
        <version>0.0.2-RELEASE</version>
    </dependency>

配置注解参数

和Lombok等注解处理器类似的配置：

<plugin>
    <groupId>org.apache.maven.plugins</groupId>
    <artifactId>maven-compiler-plugin</artifactId>
    <version>3.8.1</version>
    <configuration>
        <annotationProcessorPaths>
            <path>
                <groupId>com.iakuil</groupId>
                <artifactId>ez-mapper-processor</artifactId>
                <version>0.0.2-RELEASE</version>
            </path>
        </annotationProcessorPaths>
    </configuration>
</plugin>

配置JSON字段

@JsonEntity
public class Bar {
    private String name;
    private String addr;
    // getters and setters
}

重新编译后，target/classes目录下自动生成的TypeHandler：

@MappedTypes({Bar.class})
@MappedJdbcTypes({JdbcType.VARCHAR})
public class BarTypeHandler extends AbstractJsonTypeHandler<Bar> {
    public BarTypeHandler() {
    }
}

MyBatis配置文件

mybatis:
  type-handlers-package: com.yourdomain.sample.yourpackage

局限性

如果是多模块的Maven工程，整个工程中不能有包名+类名完全一致的JSON映射对象。
比如：A模块有一个org.sample.Foo，B模块也有一个org.sample.Foo，并且两个类都添加了@JsonEntity注解，编译时就会报错：Too many classes: org.sample.Foo。
