由于不支持身份验证类型10，因此无法连接到Postgress DB

问题描述

我最近尝试过Postgres.将其安装在本地(PostgreSQL 13.0)上.创建一个maven项目并使用Spring Data JPA，效果很好.而当我尝试使用Gradle项目时，我无法连接到数据库并不断出现以下错误.

I have recently tried my hands on Postgres. Installed it on local(PostgreSQL 13.0).Created a maven project and used Spring Data JPA, works just fine. Whereas when I tried using Gradle project, I am not able to connect to the DB and keep getting the following error.

我也尝试使用JDBCTemplate.不起作用

I tried using JDBCTemplate as well. Doesn't work

参考此修改了pg_hba.cfg文件帖子-不起作用

Modified the pg_hba.cfg file referring to this post - Doesn't work

使用了已弃用的库-也不起作用.

Used the deprecated Lib of - Doesn't Work either.

请为我建议一个解决此问题的方法.

Please Suggest me a solution for this problem.

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;

    }

}

依赖项

implementation('org.springframework.boot:spring-boot-starter-web')
    compile("org.springframework.boot:spring-boot-devtools")
    compile(group: 'org.postgresql', name: 'postgresql', version: '42.1.4')
    compile("org.springdoc:springdoc-openapi-ui:1.4.1")
    compile("org.springframework:spring-jdbc:5.2.5.RELEASE")

password_encryption设置如下:

postgres=# show password_encryption;
 password_encryption
---------------------
 scram-sha-256
(1 row)

推荐答案

我通过在PostgreSQL 版本13 中应用以下步骤解决了类似的问题:

I solved similar issue by applying below steps in PostgreSQL Version 13 :

1. 将password_encryption更改为md5.

1. Change password_encryption to md5.

文件: C:\ Program Files \ PostgreSQL \ 13 \ data \ postgresql.conf

在主机设置中将scram-sha-256更改为md5.

Change scram-sha-256 to md5 in host settings.

文件: C:\ Program Files \ PostgreSQL \ 13 \ data \ pg_hba.conf .

全部托管0.0.0.0/0 md5

host all all 0.0.0.0/0 md5

更改密码(此恢复密码为md5格式).

Change Password ( this restore password in md5 format).

示例:ALTER ROLE postgres WITH PASSWORD 'root';

如果您非生产性工作，请确保设置listen_addresses = '*'环境.

Make sure you set listen_addresses = '*' if you are working non productionenvironment.

文件:C:\Program Files\PostgreSQL\13\data\postgresql.conf
