Overview

This example will help you integrate ONLYOFFICE Docs into your web application written in Java with Spring Boot.

Spring Boot has a lot of functionality, but its most significant features are: dependency management, auto-configuration, and built-in servlet containers.

It is aimed at testing the editors. Please, do not use it for production without proper modifications.

For Windows

Step 1. Install ONLYOFFICE Docs

Download and install ONLYOFFICE Docs (packaged as Document Server).

See the detailed guide to learn how to install Document Server for Windows.

Step 2. Download the Java code for the editors integration

Download the Java-Spring example from our site.

To connect the editors to your website, specify the path to the editors installation, server address and port in the \src\main\resources\application.properties file:

 server.address=address
 server.port=port
 files.docservice.url.site=https://documentserver/

where the documentserver is the name of the server with the ONLYOFFICE Document Server installed. address is the address of the server or comment this line to use localhost, port is the any available port.

If you want to experiment with the editor configuration, modify the parameters it the \src\main\resources\editor.html file.

Step 3. Install the prerequisites

To run the Java example code, install the Java version 11 appropriate for your OS and framework Apache Maven:

• Java (download from the Oracle official website);
• Apache Maven (download from the official website).

Step 4. Set environment variables

1. After you have installed Java on Windows, set the JAVA_HOME environment variable to point to the Java installation directory.

   Find out where Java is installed. If you didn't change the path during installation, it will be something like this:

   C:\Program Files\Java\jdk11
   

   In Windows 7 right click My Computer and select Properties, then click Advanced.

   In Windows 8 go to Control Panel -> System -> Advanced System Settings.

   Click the Environment Variables button.

   Under System Variables, click New.

   In the Variable Name field, enter JAVA_HOME if you installed the JDK (Java Development Kit) or JRE_HOME if you installed the JRE (Java Runtime Environment).

   In the Variable Value field, enter your JDK or JRE installation path, for example C:\Program Files\Java\jdk11.

   Check if the variable created successfully by echo command in the Command Prompt:

   echo %JAVA_HOME%
   

2. Set the MAVEN_HOME environment variable:

   Unzip the downloaded archive with the maven to any directory, it will be something like this:

   C:\apache-maven-3.8.1
   

   In Windows 7 right click My Computer and select Properties, then click Advanced.

   In Windows 8 go to Control Panel -> System -> Advanced System Settings.

   Click the Environment Variables button.

   Under System Variables, click New.

   In the Variable Name field, enter MAVEN_HOME.

   In the Variable Value field, enter your JDK or JRE installation path, for example C:\apache-maven-3.8.1.

   Add C:\apache-maven-3.8.1\bin to the PATH system variable: In system variables, find PATH, clicks on the Edit... button. In “Edit environment variable” dialog, clicks on the New button and add this C:\apache-maven-3.8.1\bin

   Check if the variable created successfully by echo command in the Command Prompt:

   echo %MAVEN_HOME%
   

Step 5. Start application with Maven

1. Open the console and go the java-spring folder using the cd command, for example:

   cd C:\Program Files\document-server-integration\web\documentserver-example\java-spring
   

2. In the open console enter the following commands:

   mvn clean
   mvn package
   mvn spring-boot:run
   

3. Open your browser using server.address and server.port:

   http://server.address:server.port/
   

Step 6. Check accessibility

In case the example and Document Server are installed on different computers, make sure that your server with the example installed has access to the Document Server with the address which you specify instead of documentserver in the configuration files.

Make sure that the Document Server has access to the server with the example installed with the address which you specify instead of example.com in the configuration files.

For Linux

Step 1. Install ONLYOFFICE Docs

Download and install ONLYOFFICE Docs (packaged as Document Server).

See the detailed guide to learn how to install Document Server for Linux.

Step 2. Install the prerequisites and run the website with the editors

1. Install Java:

   sudo add-apt-repository ppa:webupd8team/java sudo apt-get update sudo apt-get install oracle-java11-installer
   

2. Download the archive with the Java-Spring example and unpack the archive or clone git repository:

   a) archive with Java-Spring:

   wget https://api.onlyoffice.com/app_data/editor/Java-Spring%20Example.zip
   

   unzip Java-Spring\ Example.zip
   

   b) git repository:

   git clone https://github.com/ONLYOFFICE/document-server-integration.git
   

3. Change the current directory for the project directory:

   a) from archive

   cd Java-Spring\ Example/
   

   b) from git repository

   cd document-server-integration/web/documentserver-example/java-spring
   

4. Edit the application.properties configuration file. Specify the name of your local server with the ONLYOFFICE Document Server installed.

   nano src/main/resources/application.properties
   

   Edit the following lines:

   server.address=address
   server.port=port
   files.docservice.url.site=https://documentserver/
   

   Where the documentserver is the name of the server with the ONLYOFFICE Document Server installed. address is the address of the server or comment this line to use localhost, port is the any available port.

5. Install Maven:

   sudo apt-get install maven
   

6. Build:

   mvn package
   

7. Start Java-Spring example:

   ./mvnw spring-boot:run
   

8. Open your browser using server.address and server.port:

   http://server.address:server.port/
   

Step 3. Check accessibility

In case the example and Document Server are installed on different computers, make sure that your server with the example installed has access to the Document Server with the address which you specify instead of documentserver in the configuration files.

Make sure that the Document Server has access to the server with the example installed with the address which you specify instead of example.com in the configuration files.

For Docker

1. Edit the application.properties configuration file. Specify the name of your local server with the ONLYOFFICE Document Server installed (installation instructions).

   nano src/main/resources/application.properties
   

2. Edit the following lines:

   server.address=address
   server.port=port
   files.docservice.url.site=https://documentserver/
   

   Where the documentserver is the name of the server with the ONLYOFFICE Document Server installed. address is the address of the server or comment this line to use localhost, port is the any available port.

3. Run the next command in the java example directory:

   docker-compose up
   

4. Open your browser using server.address and server.port:

   http://server.address:server.port/
