mybatis-crypt's Introduction

mybatis-crypt

mybatis 拦截器--实现数据库数据脱敏

介绍

注解类 @CryptField — 可作用于类成员变量、方法、方法参数

@Documented
@Retention(RetentionPolicy.RUNTIME)
@Target({ElementType.FIELD, ElementType.PARAMETER, ElementType.METHOD})
public @interface CryptField {

    String value() default "";

    boolean encrypt() default true;

    boolean decrypt() default true;
}

使用方法

引入jar包

配置mybatis插件

xml

<!-- 配置SqlSessionFactory -->
    <bean id="sqlSessionFactory" class="org.mybatis.spring.SqlSessionFactoryBean">
        <!-- 数据源 -->
        <property name="dataSource" ref="dataSource"/>
        <property name="mapperLocations">
            <array>
                <value>classpath:mapper/*.xml</value>
            </array>
        </property>
        <property name="plugins">
            <array>
                <bean id="cryptInterceptor" class="org.apache.ibatis.plugin.CryptInterceptor">
                </bean>
            </array>
        </property>
    </bean>

java config

@Bean(name = "sqlSessionFactory")
public SqlSessionFactory sqlSessionFactory() throws Exception {
	SqlSessionFactoryBean factoryBean = new SqlSessionFactoryBean();
	PathMatchingResourcePatternResolver resolver = new PathMatchingResourcePatternResolver();
        factoryBean.setMapperLocations(resolver.getResources("classpath:/mapper/*.xml"));
	factoryBean.setDataSource(dataSource);
  
        List<Interceptor> interceptors = Lists.newArrayList();

	CryptInterceptor cryptInterceptor = new CryptInterceptor();
	interceptors.add(cryptInterceptor);

	factoryBean.setPlugins(interceptors.toArray(new Interceptor[interceptors.size()]));

	return factoryBean.getObject();
}

注解使用场景

方法

表示返回值需要解密，适用对象包括String、List<String>、JavaBean、List<JavaBean>
```
@CryptField
List<AppInfo> select(String aaa);
```
类成员变量

表示类成员需要加解密，具体看使用场景、适用对象包括String、List<String>
方法参数

表示方法参数需要加密，适用对象包括String、List<String>、JavaBean、List<JavaBean>
