该章节次要介绍如何应用数据脱敏性能，如何进行相干配置。数据脱敏性能即可与数据分片性能独特应用，又可作为独自性能组件，独立应用。
与数据分片性能独特应用时，会创立 ShardingDataSource；独自应用时，会创立 EncryptDataSource 来实现数据脱敏性能。

不应用 Spring

引入 Maven 依赖

<dependency>
    <groupId>org.apache.shardingsphere</groupId>
    <artifactId>sharding-jdbc-core</artifactId>
    <version>${sharding-sphere.version}</version>
</dependency>

基于 Java 编码的规定配置

       // 配置数据源
       BasicDataSource dataSource = new BasicDataSource();
       dataSource.setDriverClassName("com.mysql.jdbc.Driver");
       dataSource.setUrl("jdbc:mysql://127.0.0.1:3306/encrypt");
       dataSource.setUsername("root");
       dataSource.setPassword("");
       
       // 配置脱敏规定
       Properties props = new Properties();
       props.setProperty("aes.key.value", "123456");
       EncryptorRuleConfiguration encryptorConfig = new EncryptorRuleConfiguration("AES", props);
       EncryptColumnRuleConfiguration columnConfig = new EncryptColumnRuleConfiguration("plain_pwd", "cipher_pwd", "","aes");
       EncryptTableRuleConfiguration tableConfig = new EncryptTableRuleConfiguration(Collections.singletonMap("pwd", columnConfig));
       EncryptRuleConfiguration encryptRuleConfig = new EncryptRuleConfiguration();
       encryptRuleConfig.getEncryptors().put("aes", encryptorConfig);
       encryptRuleConfig.getTables().put("t_encrypt", tableConfig);
       
       // 获取数据源对象
       DataSource dataSource = EncryptDataSourceFactory.createDataSource(dataSource, encryptRuleConfig, new Properties());

基于 Yaml 的规定配置

或通过 Yaml 形式配置，与以上配置等价：

dataSource:  !!org.apache.commons.dbcp2.BasicDataSource
  driverClassName: com.mysql.jdbc.Driver
  url: jdbc:mysql://127.0.0.1:3306/encrypt?serverTimezone=UTC&useSSL=false
  username: root
  password:

encryptRule:
  tables:
    t_order:
      columns:
        user_id:
          cipherColumn: user_cipher
          encryptor: order_encryptor
  encryptors:
    order_encryptor:
      type: aes
      props:
        aes.key.value: 123456
props:
  query.with.cipher.column: true #是否应用密文列查问
    DataSource dataSource = YamlEncryptDataSourceFactory.createDataSource(yamlFile);

应用 Spring

引入 Maven 依赖

<!-- for spring boot -->
<dependency>
    <groupId>org.apache.shardingsphere</groupId>
    <artifactId>sharding-jdbc-spring-boot-starter</artifactId>
    <version>${sharding-sphere.version}</version>
</dependency>

<!-- for spring namespace -->
<dependency>
    <groupId>org.apache.shardingsphere</groupId>
    <artifactId>sharding-jdbc-spring-namespace</artifactId>
    <version>${sharding-sphere.version}</version>
</dependency>

基于 Spring boot 的规定配置

spring.shardingsphere.datasource.name=ds

spring.shardingsphere.datasource.ds.type=org.apache.commons.dbcp2.BasicDataSource
spring.shardingsphere.datasource.ds.driver-class-name=com.mysql.jdbc.Driver
spring.shardingsphere.datasource.ds.url=jdbc:mysql://127.0.0.1:3306/encrypt?serverTimezone=UTC&useSSL=false
spring.shardingsphere.datasource.ds.username=root
spring.shardingsphere.datasource.ds.password=
spring.shardingsphere.datasource.ds.max-total=100

spring.shardingsphere.encrypt.encryptors.encryptor_aes.type=aes
spring.shardingsphere.encrypt.encryptors.encryptor_aes.props.aes.key.value=123456
spring.shardingsphere.encrypt.tables.t_order.columns.user_id.plainColumn=user_decrypt
spring.shardingsphere.encrypt.tables.t_order.columns.user_id.cipherColumn=user_encrypt
spring.shardingsphere.encrypt.tables.t_order.columns.user_id.assistedQueryColumn=user_assisted
spring.shardingsphere.encrypt.tables.t_order.columns.user_id.encryptor=encryptor_aes

spring.shardingsphere.props.sql.show=true
spring.shardingsphere.props.query.with.cipher.column=true

基于 Spring boot + JNDI 的规定配置

如果您打算应用 Spring boot + JNDI 的形式，在利用容器（如 Tomcat）中应用 Sharding-JDBC 时，可应用 spring.shardingsphere.datasource.${datasourceName}.jndiName 来代替数据源的一系列配置。
如：

spring.shardingsphere.datasource.name=ds

spring.shardingsphere.datasource.ds.jndi-name=java:comp/env/jdbc/ds

spring.shardingsphere.encrypt.encryptors.encryptor_aes.type=aes
spring.shardingsphere.encrypt.encryptors.encryptor_aes.props.aes.key.value=123456
spring.shardingsphere.encrypt.tables.t_order.columns.user_id.plainColumn=user_decrypt
spring.shardingsphere.encrypt.tables.t_order.columns.user_id.cipherColumn=user_encrypt
spring.shardingsphere.encrypt.tables.t_order.columns.user_id.assistedQueryColumn=user_assisted
spring.shardingsphere.encrypt.tables.t_order.columns.user_id.encryptor=encryptor_aes

spring.shardingsphere.props.sql.show=true
spring.shardingsphere.props.query.with.cipher.column=true

基于 Spring 命名空间的规定配置

       xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
       xmlns:encrypt="http://shardingsphere.apache.org/schema/shardingsphere/encrypt"

    <encrypt:data-source id="encryptDataSource" data-source-name="db" >
        <encrypt:encrypt-rule>
            <encrypt:tables>
                <encrypt:table name="t_order">
                    <encrypt:column logic-column="user_id" plain-column="user_decrypt" cipher-column="user_encrypt" assisted-query-column="user_assisted" encryptor-ref="encryptor_aes" />

                </encrypt:table>
            </encrypt:tables>
            <encrypt:encryptors>
                <encrypt:encryptor id="encryptor_aes" type="AES" props-ref="props"/>
                <encrypt:encryptor id="encryptor_md5" type="MD5" />
            </encrypt:encryptors>
        </encrypt:encrypt-rule>
        <encrypt:props>
            <prop key="sql.show">true</prop>
            <prop key="query.with.cipher.column">true</prop>
        </encrypt:props>
    </encrypt:data-source>
</beans>

在 Spring 中应用 DataSource

间接通过注入的形式即可应用 DataSource，或者将 DataSource 配置在 JPA、Hibernate 或 MyBatis 中应用。

@Resource
private DataSource dataSource;
