Config druid datasource as below:

`

@Bean(name = chanceDataSourceMaster, initMethod = "init", destroyMethod = "close")
@Primary
@Qualifier
public DruidDataSource dataSourceMaster() throws SQLException {
    return getDruidDataSource(driverClassName, dbMaterUrl, dbMaterUsername, dbMaterPassword);
}

@Bean(name = "chanceDataSourceSlave", initMethod = "init", destroyMethod = "close")
@Qualifier
public DruidDataSource dataSourceSlave() throws SQLException {
    return getDruidDataSource(driverClassName, dbSlaveUrl, dbSlaveUsername, dbSlavePassword);
}

private DruidDataSource getDruidDataSource(String driverClassName, String jdbcUrl, String username, String password) throws SQLException {
    DruidDataSource dataSource = new DruidDataSource();
    dataSource.setDriverClassName(driverClassName);
    dataSource.setUrl(jdbcUrl);
    dataSource.setUsername(username);
    dataSource.setPassword(password);
    dataSource.setMaxActive(this.maxActive);
    dataSource.setInitialSize(this.initialSize);
    dataSource.setMinIdle(this.minIdle);
    dataSource.setTimeBetweenEvictionRunsMillis(10000);
    dataSource.setMinEvictableIdleTimeMillis(30000);
    dataSource.setValidationQuery("SELECT 'x'");
    dataSource.setTestWhileIdle(true);
    dataSource.setTestOnBorrow(false);
    dataSource.setTestOnReturn(false);
    dataSource.setRemoveAbandoned(true);
    dataSource.setRemoveAbandonedTimeout(1800);
    dataSource.setLogAbandoned(true);
    dataSource.setFilters("stat");
    dataSource.setConnectionProperties("druid.stat.slowSqlMillis=100");

    //设置sql连接字符编码 utf8mb4
    Set<String> set = new HashSet<>();
    set.add("set names utf8mb4;");
    dataSource.setConnectionInitSqls(set);
    return dataSource;
}`
