我的春季啓動應用程序的新版本無法連接到mysql

Question

我的春季啓動應用程序在本地主機上運行良好，它已經生活了幾個月的第一個版本工作正常，但現在當我嘗試上傳應用程序的新版本，或任何其他春天啓動的應用程序，我得到以下錯誤：

下面是我的應用程序屬性文件：

spring.jpa.hibernate.ddl-auto=update 
 

 
# Replace with your connection string 
 
spring.datasource.url=jdbc:mysql://127.0.0.1:3306/appName 
 
spring.datasource.connectionProperties=useUnicode=true;characterEncoding=utf-8; 
 

 
# Replace with your credentials 
 
spring.datasource.username=root 
 
spring.datasource.password=root 
 

 

 
# Keep the connection alive if idle for a long time (needed in production) 
 
spring.datasource.testWhileIdle = true 
 
spring.datasource.validationQuery = SELECT 1 
 

 
spring.datasource.test-on-borrow=true 
 
spring.datasource.connection-test-query=SELECT 1 
 
spring.datasource.tomcat.validation-interval=0 
 
# Number of ms to wait before throwing an exception if no connection is available. 
 
spring.datasource.tomcat.max-wait=10000 
 

 
# Validate the connection before borrowing it from the pool. 
 
spring.datasource.tomcat.test-on-borrow=true 
 

 

 
spring.datasource.driver-class-name=com.mysql.jdbc.Driver 
 
#spring.jpa.database-platform=org.hibernate.dialect.MySQL5InnoDBDialect 
 

 
# The SQL dialect makes Hibernate generate better SQL for the chosen database 
 
spring.jpa.properties.hibernate.dialect = org.hibernate.dialect.MySQL5Dialect 
 
#server.port = 8081

因此，已經檢查MySQL正在運行，我能夠用工作臺和1個實時應用程序連接到它如前所述，我並沒有把錯誤的用戶名/密碼，或作出申請的任何更改.properties文件導致問題，並且問題僅在Spring引導應用程序中出現，而Spring應用程序運行良好。 我正在使用Jenkins在Tomcat上部署應用程序，上面發佈的錯誤輸出來自jenkins。

Answer 1

我把它固定方式：編輯在位於/etc/mysql/mysql.conf mysqlId.cnf文件綁定地址。 d /目錄，看起來像這樣：
綁定地址= 0.0.0.0

和重裝mysql服務之後。

然後，我創建了一個授予新的用戶如下：

CREATE USER '爲myuser' @ 'localhost' 的IDENTIFIED BY '爲mypass'; CREATE USER'myuser'@'％'IDENTIFIED BY'mypass';

GRANT ALL ON 。 TO'myuser'@'localhost'; GRANT ALL ON 。 TO'myuser'@'％';

和沖洗特權：

FLUSH特權;

Answer 2

java.sql.SQLException: Access denied for user 'root'@'localhost' (using password: YES)

這是一個權限問題。您必須使用GRANT權限才能使用給定的用戶名和密碼從該客戶端連接到該主機。我不會建議給任何應用程序root訪問數據庫。爲您的應用程序創建應用程序憑據到特定數據庫。

你讓這個過於複雜。春天，詹金斯，雄貓等不是你的問題。寫一個簡單的main方法做一個JDBC連接，像這樣：

package database.util; 

import org.mariadb.jdbc.MySQLDataSource; 

import javax.sql.DataSource; 
import java.sql.Connection; 
import java.sql.DatabaseMetaData; 
import java.sql.DriverManager; 
import java.sql.ResultSet; 
import java.sql.SQLException; 
import java.sql.Statement;
