创建DataSource时出错

Question

我得到一个spring boot应用程序，并尝试创建一个由Java配置定义的DataSource bean：

@Bean(name = "dsBD") @Primary
public DataSource dsBD() {
  return DataSourceBuilder.create()
    .url("jdbc:mysql://localhost:3306/‌​database?autoReconne‌​ct=true")
    .username("‌​root")
    .password("mysql")
    .driverClassName("com.mysql.jdbc.Drive‌​r")
    .build();
}

@Bean(name = "jdbcBD") @Autowired
public JdbcTemplate jdbcBD(@Qualifier("dsBD") DataSource dsBD) {
  return new JdbcTemplate(dsBD);
}

但是在启动应用程序时，我收到以下错误：

Answer 1

就使用DataSourceBuilder而言，您需要在类路径中使用以下其中一项：

1. 公地DBCP
2. TOMCAT-JDBC
3. HIKARICP

否则，您现在可以获得IllegalStateException没有支持的类型。
