前端（HTML）无法从Microsoft Azure中的mysql数据库中获取Spring Boot应用程序中的数据

Question

I am trying to fetch data from MySQL database which is hosted in Microsoft Azure and my spring boot maven app is also deployed in Azure.

When I am hitting my data hosting link, it displays data in JSON format on a web browser. For Example - https://xyz.azurewebsites.net/checklist displays data in JSON format.

On the other end When I am hitting my front-end link, it displays my design. For Example - https://xyz.azurewebsites.net/search.html displays HTML view.

Note - This complete app working fine on local server //localhost/3306. But it is not running fine when I am deploying it on Microsoft Azure. Kind of mismatch issue.

Where am I doing a mistake?

Application.properties (I am naive so I just learned and tried to implement. Is application.properties is correct? It allow me to connect mysql with azure from local host also)

spring.datasource.driver-class-name=com.mysql.cj.jdbc.Driver


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

# Show or not log for each sql query
spring.jpa.show-sql = true

# Hibernate ddl auto (create, create-drop, update)
spring.jpa.hibernate.ddl-auto = update

# Naming strategy
spring.jpa.hibernate.naming-strategy =     org.hibernate.cfg.ImprovedNamingStrategy

# Use spring.jpa.properties.* for Hibernate native properties (the prefix is
# stripped before adding them to the entity manager)

# The SQL dialect makes Hibernate generate better SQL for the chosen     database
spring.jpa.properties.hibernate.dialect =     org.hibernate.dialect.MySQL5Dialect
logging.level.org.hibernate.SQL:debug

#naming convention according to me
spring.jpa.hibernate.naming.physical-    strategy=org.hibernate.boot.model.naming.PhysicalNamingStrategyStandardImpl

What stuff Am I doing wrong? Is that hosting link issue?

Answer 1

According to your description, your project works fine locally, so consider the issue of deployment.

You could followed the official tutorials to deploy spring-boot project to azure.

Combining the steps in the official tutorials and your actual situation, I provide the following check points:

Point 1: Please use mvn package to bulid the JAR package in the directory under which the pom.xml file is located.

]

Point 2: Please make sure that the jar package name configured in web.config is the same as the uploaded jar package name.

Point 3: Please use FTP to publish jar files and web.config to D:\\home\\site\\wwwroot\\ directory on KUDU.

Point 4: Please make sure ApplicationSettings matches your project such as jdk version , tomcat version .

If you want to deploy a war file, you need to configure the ApplicationSettings of your app service on Azure portal, then upload the war file into the path D:\\home\\site\\wwwroot\\webapps .

As references, please refer to the documents and threads below.

1. Configure web apps in Azure App Service

2. Create a Java web app in Azure App Service

3. Deploying Springboot to Azure App Service .

Hope it helps you.
