druid 多數據源配置

新建兩個數據源配置類：DruidDataSourceMasterConfigurer.java和DruidDataSourceAddressBookConfigurer.java

DruidDataSourceMasterConfigurer.java代碼如下

@EnableAutoConfiguration(exclude = {DataSourceAutoConfiguration.class})
@Configuration
@MapperScan(basePackages = DruidDataSourceMasterConfigurer.PACKAGE, sqlSessionFactoryRef = "sqlSessionFactoryMaster")
@Primary
public class DruidDataSourceMasterConfigurer {

    /**
     * dao層的包路徑
     */
    static final String PACKAGE = "com.dienphuoc.select.user.depart.dao.department_user";

    /**
     * Mapper文件路徑
     */
    @Value("${mybatis.mapper-locations}")
    private String mapperLocation;

    @Value("${spring.druid.master.publicKey}")
    private String publicKey;
    @Value("${spring.druid.master.decrypt}")
    private String decrypt;

    /**
     * @ConfigurationProperties(prefix = "配置文件中數據源路徑")
     * @Bean(name = "配置文件中數據源名稱", initMethod = "init", destroyMethod = "close")
     */
    @ConfigurationProperties(prefix = "spring.druid.master")
    @Bean(name = "master", initMethod = "init", destroyMethod = "close")
    public DruidDataSource dataSource() {
        DruidDataSource dataSource = new DruidDataSource();
        dataSource.setProxyFilters(Lists.newArrayList(statFilter(), configFilter()));
        Properties properties = new Properties();
        properties.setProperty("config.decrypt", decrypt);
        properties.setProperty("config.decrypt.key", publicKey);
        dataSource.setConnectProperties(properties);
        return dataSource;
    }

    @Bean("txManager")
    public DataSourceTransactionManager txManager() {
        return new DataSourceTransactionManager(dataSource());
    }

    /**
     * 定義空Config類用於加密類的加載
     */
    @Bean
    public ConfigFilter configFilter() {
        ConfigFilter configFilter = new ConfigFilter();
        return configFilter;
    }

    /**
     * 配置了要打印的sql
     */
    @Bean
    public Filter statFilter() {
        StatFilter filter = new StatFilter();
        filter.setSlowSqlMillis(2000);
        filter.setLogSlowSql(true);
        filter.setMergeSql(true);
        return filter;
    }

    @Bean
    public ServletRegistrationBean servletRegistrationBean() {
        return new ServletRegistrationBean(new StatViewServlet(), "/druid/*");
    }


    /**
     * @Bean(name = "Bean實例名")
     * @Qualifier("數據源名稱")
     */
    @Bean(name = "sqlSessionFactoryMaster")
    public SqlSessionFactory sqlSessionFactoryMaster(@Qualifier("master") DataSource datasource)
            throws Exception {
        SqlSessionFactoryBean bean = new SqlSessionFactoryBean();
        bean.setDataSource(datasource);
        bean.setMapperLocations(
                new PathMatchingResourcePatternResolver().getResources(mapperLocation));
        return bean.getObject();
    }
}

DruidDataSourceAddressBookConfigurer.java代碼如下

@EnableAutoConfiguration(exclude = {DataSourceAutoConfiguration.class})
@Configuration
@MapperScan(basePackages = DruidDataSourceAddressBookConfigurer.PACKAGE, sqlSessionFactoryRef = "sqlSessionFactoryAddress")
public class DruidDataSourceAddressBookConfigurer {

    /**
     * dao層的包路徑
     */
    static final String PACKAGE = "com.dienphuoc.select.user.depart.dao.address_book";

    /**
     * Mapper文件路徑
     */
    @Value("${mybatis.mapper-locations}")
    private String mapperLocation;

    @Value("${spring.druid.address.publicKey}")
    private String publicKey;
    @Value("${spring.druid.address.decrypt}")
    private String decrypt;

    /**
     * @ConfigurationProperties(prefix = "配置文件中數據源路徑")
     * @Bean(name = "配置文件中數據源名稱", initMethod = "init", destroyMethod = "close")
     */
    @ConfigurationProperties(prefix = "spring.druid.address")
    @Bean(name = "address", initMethod = "init", destroyMethod = "close")
    public DruidDataSource dataSource() {
        DruidDataSource dataSource = new DruidDataSource();
        dataSource.setProxyFilters(Lists.newArrayList(statFilterAddress(), configFilterAddress()));
        Properties properties = new Properties();
        properties.setProperty("config.decrypt", decrypt);
        properties.setProperty("config.decrypt.key", publicKey);
        dataSource.setConnectProperties(properties);
        return dataSource;
    }

    @Bean("txManagerAddress")
    public DataSourceTransactionManager txManagerAddress() {
        return new DataSourceTransactionManager(dataSource());
    }

    /**
     * 定義空Config類用於加密類的加載
     */
    @Bean
    public ConfigFilter configFilterAddress() {
        ConfigFilter configFilter = new ConfigFilter();
        return configFilter;
    }

    /**
     * 配置了要打印的sql
     */
    @Bean
    public Filter statFilterAddress() {
        StatFilter filter = new StatFilter();
        filter.setSlowSqlMillis(2000);
        filter.setLogSlowSql(true);
        filter.setMergeSql(true);
        return filter;
    }

    @Bean
    public ServletRegistrationBean servletRegistrationBeanAddress() {
        return new ServletRegistrationBean(new StatViewServlet(), "/druid/*");
    }


    /**
     * @Bean(name = "Bean實例名")
     * @Qualifier("數據源名稱")
     */
    @Bean(name = "sqlSessionFactoryAddress")
    public SqlSessionFactory sqlSessionFactoryAddress(@Qualifier("address") DataSource datasource)
            throws Exception {
        SqlSessionFactoryBean bean = new SqlSessionFactoryBean();
        bean.setDataSource(datasource);
        bean.setMapperLocations(
                new PathMatchingResourcePatternResolver().getResources(mapperLocation));
        return bean.getObject();
    }
}
application.xml配置如下

druid:
  master:
    url: jdbc:mysql://192.168.250.101:3306/bbb?useUnicode=true&characterEncoding=utf-8&autoReconnect=true&failOverReadOnly=false&useSSL=false&serverTimezone=Asia/Shanghai&rewriteBatchedStatements=true
    username: root
    password: pbbbb
    driver-class-name: com.mysql.jdbc.Driver
    type: com.alibaba.druid.pool.DruidDataSource
    initialSize: 1  #初始化大小
    minIdle: 5      #最小連接數
    maxActive: 20   #最大連接數
    maxWait: 60000  #最大等待時間
    validationQuery: select '1'   #活性校驗SQL
    testWhileIdle: true
    testOnBorrow: false
    testOnReturn: false
    timeBetweenEvictionRunsMillis: 60000  #配置隔多久進行一次檢測(檢測可以關閉的空閑連接)，檢測需要關閉的空閑連接，單位是毫秒
    filters: stat,wall,slf4j #配置監控統計攔截的filters，去掉后監控界面sql無法統計，'wall'用於防火牆
    publicKey: publicKey
    decrypt: false
  address:
    url: jdbc:mysql://localhost:3306/aaa?useUnicode=true&characterEncoding=utf-8&autoReconnect=true&failOverReadOnly=false&useSSL=false&serverTimezone=Asia/Shanghai&rewriteBatchedStatements=true
    username: root
    password: eee
    driver-class-name: com.mysql.jdbc.Driver
    type: com.alibaba.druid.pool.DruidDataSource
    initialSize: 1  #初始化大小
    minIdle: 5      #最小連接數
    maxActive: 20   #最大連接數
    maxWait: 60000  #最大等待時間
    validationQuery: select '1'   #活性校驗SQL
    testWhileIdle: true
    testOnBorrow: false
    testOnReturn: false
    timeBetweenEvictionRunsMillis: 60000  #配置隔多久進行一次檢測(檢測可以關閉的空閑連接)，檢測需要關閉的空閑連接，單位是毫秒
    filters: stat,wall,slf4j #配置監控統計攔截的filters，去掉后監控界面sql無法統計，'wall'用於防火牆
    publicKey: publicKey
    decrypt: false

配置完成，結束。
