由于不支持身份验证类型 10,无法连接到 Postgres DB
我最近在Postgres上尝试了一下。将其安装在本地(PostgreSQL 13.0)。创建了一个maven项目并使用Spring Data JPA,工作正常。然而,当我尝试使用Gradle项目时,我无法连接到数据库并继续收到以下错误。
org.postgresql.util.PSQLException:不支持身份验证类型 10。检查是否已将 pg_hba.conf 文件配置为包含客户端的 IP 地址或子网,以及它是否正在使用驱动程序支持的身份验证方案。at org.postgresql.core.v3.ConnectionFactoryImpl.doAuthentication(ConnectionFactoryImpl.java:614) ~[postgresql-42.1.4.jar:42.1.4] at org.postgresql.core.v3.ConnectionFactoryImpl.openConnectionImpl(ConnectionFactoryImpl.java:222) ~[postgresql-42.1.4.jar:42.1.4] at org.postgresql.core.ConnectionFactory.openConnection(ConnectionFactory.java:49) ~[postgresql-42.1.4.jar:42.1.4] at org.postgresql.jdbc.PgConnection.(PgConnection.java:194) ~[postgresql-42.1.4.jar:42.1.4] at org.postgresql.Driver.makeConnection(Driver.java:450) ~[postgresql-42.1.4.jar:42.1.4] at org.postgresql.Driver.connect(Driver.java:252) ~[postgresql-4 2.1.4.jar:42.1.4] at java.sql.DriverManager.getConnection(Unknown Source) [na:1.8.0_261] at java.sql.DriverManager.getConnection(Unknown Source) [na:1.8.0_261] at org.postgresql.ds.common.BaseDataSource.getConnection(BaseDataSource.java:94) [postgresql-42.1.4.jar:42.1.4] at org.postgresql.ds.common.BaseDataSource.getConnection(BaseDataSource.java:79) [postgresql-42.1.4.jar:42.1.4]
我也尝试使用JDBCTemplate。不起作用
修改了引用此帖子pg_hba.cfg文件 - 不起作用
使用了已弃用的 Lib - 也不起作用。
请建议我解决这个问题。
我的代码和配置:
@Configuration
public class DataSourceConfig {
@Bean
public DriverManagerDataSource getDataSource() {
DriverManagerDataSource dataSourceBuilder = new DriverManagerDataSource();
dataSourceBuilder.setDriverClassName("org.postgresql.Driver");
dataSourceBuilder.setUrl("jdbc:postgresql://localhost:5432/postgres");
dataSourceBuilder.setUsername("postgres");
dataSourceBuilder.setPassword("root");
return dataSourceBuilder;
}
}
@Component
public class CustomerOrderJDBCTemplate implements CustomerOrderDao{
private DataSource dataSource;
private JdbcTemplate jdbcTemplateObject;
@Autowired
ApplicationContext context;
public void setDataSource() {
//Getting Bean by Class
DriverManagerDataSource dataSource = context.getBean(DriverManagerDataSource.class);
this.dataSource = dataSource;
this.jdbcTemplateObject = new JdbcTemplate(this.dataSource);
}
@Override
public Customer create(Customer customer) {
setDataSource();
String sql = "insert into CustomerOrder (customerType, customerPayment) values (?, ?)";
//jdbcTemplateObject.update(sql, customerOrder.getCustomerOrderType(), customerOrder.getCustomerOrderPayment());
KeyHolder holder = new GeneratedKeyHolder();
jdbcTemplateObject.update(new PreparedStatementCreator() {
@Override
public PreparedStatement createPreparedStatement(Connection connection) throws SQLException {
PreparedStatement ps = connection.prepareStatement(sql, Statement.RETURN_GENERATED_KEYS);
ps.setString(1, customer.getType());
ps.setString(2, customer.getPayment());
return ps;
}
}, holder);
long customerId = holder.getKey().longValue();
customer.setCustomerID(customerOrderId);
return customer;
}
}
