本文详细解析了Eureka服务注册中心启动时报错的原因，主要由于无法解析eureka02主机名，导致请求执行失败。文章提供了修改配置文件，设置eureka.client.register-with-eureka和eureka.client.fetch-registry为false的解决方案。

eureka会自动注册自己，必须设置下面属性

eureka.client.register-with-eureka=false
eureka.client.fetch-registry=false

改完重启就行了

若是a[i]>a[i+1],b[i]=b[i+1]+1，每次都取b[i]的最大值，因为最高峰正着已经求过一次，最高峰必须比两边都要大，若是反着求最高峰，小于其原本的值，则最高峰的值不变,若是a[i]==a[i+1],则b[i]=b[i+1];如果|a-c|=|b-d|>0，则(a,b)与(b,d)在同一对角线上， 要是A(a,b),A(c,d)在同一条对角线上，要么a-b=c-d,要么a+b=c+d。

eureka.client.register-with-eureka: false #是否将自己注册到eureka中。eureka.client.fetch-registry: false #是否从eureka中拉去信息列表。要先启动Eureka-server，再启动其他服务。否则其他服务也可能报错。eureka会自动注册自己，需添加以下注释，添加后重启服务即可。

其次，如果你的eureka服务端启动报错：Request execution error. endpoint=DefaultEndpoint{ serviceUrl='http://localhost:8761/eureka/}。有的时候还是识别不到eureka服务端配置信息，那就把eureka服务端的端口配置为springcloud默认的端口：http://localhost:8761/eureka/首先，需要先启动eureka服务端，再去启动各个eureka客户端。

<think>根据错误日志，现在的问题变成了"Unknowndatabase'club_db'"，这意味着在MySQL服务器中不存在名为`club_db`的数据库。解决方案：1.在MySQL中创建数据库`club_db`。2.或者，修改`application.properties`中的数据库名称为一个已存在的数据库。步骤：1.登录MySQL（例如使用命令行或MySQLWorkbench）。2.执行SQL语句创建数据库：`CREATEDATABASEclub_db;`3.确保数据库用户（这里是root）有权限访问这个数据库。如果不想创建新数据库，也可以修改配置中的数据库名称，指向一个已有的数据库。另外，在配置文件中，我们之前已经配置了Hibernate的ddl-auto为update，这样在应用启动时，Hibernate会自动创建表结构（但不会创建数据库本身）。所以必须先确保数据库存在。如果希望SpringBoot在启动时自动创建数据库（注意：不是表，而是数据库），我们可以使用一个初始化脚本，但这通常不是标准做法。标准做法是提前创建好数据库。因此，请先手动创建数据库。如果已经创建了数据库但仍然出现此错误，请检查：1.数据库名称是否正确（大小写敏感？）2.数据库服务器地址和端口是否正确3.用户名和密码是否正确修改后的`application.properties`中数据库连接字符串如下：```spring.datasource.url=jdbc:mysql://localhost:3306/club_db?useSSL=false&allowPublicKeyRetrieval=true&serverTimezone=UTC```请确保`localhost:3306`是你的MySQL服务器地址，如果不是，请修改为正确的主机和端口。另外，注意MySQL的版本，如果使用的是MySQL5.x，可能需要将方言改为`MySQL5Dialect`，但错误日志中显示已经使用了`MySQL8Dialect`，所以请确认你使用的是MySQL8。如果问题依然存在，可以尝试在连接字符串中添加其他参数，比如`createDatabaseIfNotExist=true`，但这不是标准JDBCURL参数。MySQL的JDBC驱动并不支持这个参数。所以还是需要手动创建数据库。因此，请按照以下步骤操作：1.登录MySQL：`mysql-uroot-p`，然后输入密码（你配置的密码，这里是123456）。2.执行：`CREATEDATABASEIFNOTEXISTSclub_db;`3.退出MySQL，重新启动应用。如果创建数据库后仍然有问题，请检查数据库名称是否有拼写错误，以及是否在正确的MySQL实例中。另外，如果MySQL服务器配置了大小写敏感（例如Linux系统上默认是大小写敏感的），那么请确保数据库名称的大小写与连接字符串中的完全一致。如果问题解决，应用应该能正常启动并创建表结构。如果还是无法解决，请检查MySQL用户root是否有权限访问数据库club_db。可以使用以下命令授权：```sqlGRANTALLPRIVILEGESONclub_db.*TO'root'@'localhost';FLUSHPRIVILEGES;```注意：根据你的MySQL配置，root用户可能已经拥有所有权限，但如果在连接时使用了不同的主机（比如不是localhost），则需要相应调整。总结：当前错误是因为数据库不存在，需要手动创建。</think>### 解决 "Unknown database 'club_db'" 错误 从错误日志可以看出，应用程序无法连接到MySQL数据库，因为数据库 `club_db` 不存在： ``` java.sql.SQLSyntaxErrorException: Unknown database 'club_db' ``` #### 解决方案 1. **创建数据库**：在MySQL中手动创建数据库 `club_db` 2. **自动创建数据库**：修改JDBC URL配置，让应用程序自动创建数据库 ### 方法1：手动创建数据库（推荐） 使用MySQL客户端执行以下SQL命令： ```sql CREATE DATABASE club_db CHARACTER SET utf8mb4 COLLATE utf8mb4_unicode_ci; ``` ### 方法2：自动创建数据库（开发环境适用） 修改 `application.properties` 中的JDBC URL，添加 `createDatabaseIfNotExist=true` 参数： ```properties # application.properties # 修改后的数据库连接配置 spring.datasource.url=jdbc:mysql://localhost:3306/club_db?createDatabaseIfNotExist=true&useSSL=false&allowPublicKeyRetrieval=true&serverTimezone=UTC spring.datasource.username=root spring.datasource.password=123456 spring.datasource.driver-class-name=com.mysql.cj.jdbc.Driver ``` ### 完整的 application.properties 配置 ```properties # ===== 服务器配置 ===== server.port=8080 # ===== 数据库配置 ===== spring.datasource.url=jdbc:mysql://localhost:3306/club_db?createDatabaseIfNotExist=true&useSSL=false&allowPublicKeyRetrieval=true&serverTimezone=UTC spring.datasource.username=root spring.datasource.password=123456 spring.datasource.driver-class-name=com.mysql.cj.jdbc.Driver # ===== JPA/Hibernate 配置 ===== spring.jpa.hibernate.ddl-auto=update spring.jpa.show-sql=true spring.jpa.properties.hibernate.format_sql=true spring.jpa.properties.hibernate.jdbc.batch_size=20 spring.jpa.properties.hibernate.order_inserts=true spring.jpa.properties.hibernate.order_updates=true spring.jpa.properties.hibernate.dialect=org.hibernate.dialect.MySQL8Dialect # ===== 文件上传配置 ===== spring.servlet.multipart.max-file-size=5MB spring.servlet.multipart.max-request-size=10MB app.upload.dir=uploads # ===== Thymeleaf 配置 ===== spring.thymeleaf.cache=false spring.thymeleaf.mode=HTML spring.thymeleaf.prefix=classpath:/templates/ spring.thymeleaf.suffix=.html # ===== 安全配置 ===== spring.security.user.name=admin spring.security.user.password=adminpass spring.security.user.roles=ADMIN # ===== 日志配置 ===== logging.level.root=INFO logging.level.com.example.club=DEBUG # ===== 自定义配置 ===== app.default-avatar=/images/default-avatar.jpg ``` ### 验证数据库创建 添加一个数据库初始化检查类： ```java package com.example.club.config; import org.springframework.boot.CommandLineRunner; import org.springframework.jdbc.core.JdbcTemplate; import org.springframework.stereotype.Component; @Component public class DatabaseChecker implements CommandLineRunner { private final JdbcTemplate jdbcTemplate; public DatabaseChecker(JdbcTemplate jdbcTemplate) { this.jdbcTemplate = jdbcTemplate; } @Override public void run(String... args) { try { jdbcTemplate.execute("USE club_db"); System.out.println("✅ 数据库 club_db 存在且可访问"); // 检查用户表是否存在 jdbcTemplate.queryForObject( "SELECT COUNT(*) FROM information_schema.tables " + "WHERE table_schema = 'club_db' AND table_name = 'user'", Integer.class ); System.out.println("✅ 用户表已存在"); } catch (Exception e) { System.err.println("❌ 数据库访问错误: " + e.getMessage()); System.err.println("请确保 MySQL 服务已启动，且用户有创建数据库的权限"); } } } ``` ### 权限问题解决方案 如果遇到权限错误，需要授予用户创建数据库的权限： ```sql -- 在 MySQL 中执行 GRANT ALL PRIVILEGES ON *.* TO 'root'@'localhost' WITH GRANT OPTION; FLUSH PRIVILEGES; ``` ### 数据库连接测试代码 ```java package com.example.club.util; import java.sql.Connection; import java.sql.DriverManager; import java.sql.SQLException; public class DatabaseTest { public static void main(String[] args) { String url = "jdbc:mysql://localhost:3306/mysql?useSSL=false"; String user = "root"; String password = "123456"; try (Connection conn = DriverManager.getConnection(url, user, password)) { System.out.println("✅ 成功连接到 MySQL 服务器"); // 尝试创建数据库 conn.createStatement().execute("CREATE DATABASE IF NOT EXISTS club_db"); System.out.println("✅ 数据库 club_db 创建/验证成功"); // 切换到新数据库 conn.createStatement().execute("USE club_db"); System.out.println("✅ 成功切换到 club_db 数据库"); } catch (SQLException e) { System.err.println("❌ 数据库连接失败: " + e.getMessage()); System.err.println("请检查以下配置:"); System.err.println("1. MySQL 服务是否运行"); System.err.println("2. 用户名/密码是否正确"); System.err.println("3. 用户是否有创建数据库的权限"); } } } ``` ### 常见问题排查 1. **MySQL服务未运行**： ```bash # Windows net start mysql # Linux/macOS sudo systemctl start mysql ``` 2. **用户权限不足**： ```sql CREATE USER 'club_user'@'localhost' IDENTIFIED BY 'secure_password'; GRANT ALL PRIVILEGES ON club_db.* TO 'club_user'@'localhost'; FLUSH PRIVILEGES; ``` 3. **防火墙阻止连接**： ```bash # 开放MySQL端口（默认3306） sudo ufw allow 3306 ``` 4. **修改连接配置**： ```properties # 如果MySQL运行在不同端口或主机 spring.datasource.url=jdbc:mysql://your-server:3307/club_db?... ``` ### 总结 1. **核心问题**：MySQL中不存在 `club_db` 数据库 2. **解决方案**： - 手动创建数据库 - 或在JDBC URL中添加 `createDatabaseIfNotExist=true` 参数 3. **权限要求**：确保数据库用户有创建数据库的权限 4. **验证步骤**：使用测试代码验证数据库连接和创建能力
