How to connect to Dynamics CRM Data from Spring Boot



Connect to Dynamics CRM in a Spring Boot Application using CData JDBC Dynamics CRM Driver

Spring Boot is a framework that makes engineering Java web applications easier. It offers the ability to create standalone applications with minimal configuration. When paired with the CData JDBC driver for Dynamics CRM, Spring Boot can work with live Dynamics CRM data. This article shows how to configure data sources and retrieve data in your Java Spring Boot Application, using the CData JDBC Driver for Dynamics CRM.

With built-in optimized data processing, the CData JDBC Driver offers unmatched performance for interacting with live Dynamics CRM data. When you issue complex SQL queries to Dynamics CRM, the driver pushes supported SQL operations, like filters and aggregations, directly to Dynamics CRM and utilizes the embedded SQL engine to process unsupported operations client-side (often SQL functions and JOIN operations). Its built-in dynamic metadata querying allows you to work with and analyze Dynamics CRM data using native data types.

Creating the Spring Boot Project in Java

In an IDE (in this tutorial, we use IntelliJ), choose a Maven project: In the generated project, go to the pom.xml file, and add the required dependencies for Spring Boot:

<?xml version="1.0" encoding="UTF-8"?> <project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 https://maven.apache.org/xsd/maven-4.0.0.xsd"> <modelVersion>4.0.0</modelVersion> <parent> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-parent</artifactId> <version>2.7.2</version> <relativePath/> </parent> <groupId>com.example</groupId> <artifactId>demo</artifactId> <version>0.0.1-SNAPSHOT</version> <name>demo</name> <description>Demo project for Spring Boot</description> <properties> <java.version>1.8</java.version> </properties> <build> <plugins> <plugin> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-maven-plugin</artifactId> </plugin> <plugin> <groupId>org.apache.maven.plugins</groupId> <artifactId>maven-install-plugin</artifactId> <version>2.5.1</version> <executions> <execution> <id>id.install-file</id> <phase>clean</phase> <goals> <goal>install-file</goal> </goals> <configuration> <file>C:\Program Files\CData[product_name] ####\lib\cdata.jdbc.dynamicscrm.jar</file> <groupId>org.cdata.connectors</groupId> <artifactId>cdata-dynamicscrm-connector</artifactId> <version>23</version> <packaging>jar</packaging> </configuration> </execution> </executions> </plugin> </plugins> </build> <dependencies> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-web</artifactId> </dependency> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-jdbc</artifactId> <version>2.7.0</version> </dependency> <dependency> <groupId>org.cdata.connectors</groupId> <artifactId>cdata-dynamicscrm-connector</artifactId> <version>23</version> </dependency> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-test</artifactId> <scope>test</scope> </dependency> </dependencies> <distributionManagement> <repository> <uniqueVersion>false</uniqueVersion> <id>test</id> <name>My Repository</name> <url>scp://repo/maven2</url> <layout>default</layout> </repository> </distributionManagement> </project>

Note: The year (####) and the version number (as seen in the provided XML script) should be adjusted according to the current version of the CData JDBC driver being utilized.

Project Structure

In the java directory, create a new package. Usually the name of the package is the name of the groupId (com.example) followed by the artifactId (.MDS).

Mark the "java" directory as the "Sources Root" (denoted by a blue color). To do this, right-click the java directory and choose Mark Directory as -> Sources Root (As shown below). Additionally, mark the "resources" directory as the "Resources Root."

Store Database Connection Properties

Create an "application.properties" file to store the database connection properties. To do this, right-click on the "resources" folder, opt for New -> File, input the file name as "application.properties," and press Enter.

In the application.properties file, we set the configuration properties for the Dynamics CRM JDBC Driver, using the Class name and JDBC URL:

spring.datasource.driver=cdata.jdbc.dynamicscrm.DynamicsCRMDriver spring.datasource.url=jdbc:dynamicscrm:User=myuseraccount;Password=mypassword;URL=https://myOrg.crm.dynamics.com/;CRM Version=CRM Online;

Built-in Connection String Designer

For assistance in constructing the JDBC URL, use the connection string designer built into the Dynamics CRM JDBC Driver. Either double-click the JAR file or execute the jar file from the command-line.

java -jar cdata.jdbc.dynamicscrm.jar

The connection string options meet the authentication and connection requirements of different Dynamics CRM instances. To connect to your instance, set the User and Password properties, under the Authentication section, to valid Dynamics CRM user credentials and set the Url to a valid Dynamics CRM server organization root. Additionally, set the CRMVersion property to 'CRM2011+' or 'CRMOnline'. IFD configurations are supported as well; set InternetFacingDeployment to true.

Additionally, you can provide the security token service (STS) or AD FS endpoint in the STSURL property. This value can be retrieved with the GetSTSUrl stored procedure. Office 365 users can connect to the default STS URL by simply setting CRMVersion.

After setting the properties in the application.properties file, we now configure them.

Data Source Configuration

First, we mark the Dynamics CRM data source as our primary data source. Then, we create a Data Source Bean.

Create a DriverManagerDataSource.java file and create a Bean within it, as shown below. If @Bean gives an error, Spring Boot may not have loaded properly. To fix this, go to File -> Invalidate Caches and restart. Additionally, make sure that Maven has added the Spring Boot dependencies.

To create a data source bean, we use the DriverManagerDataSource Class. This class allows us to set the properties of the data source. To create this Java class, right-click on "com.example.MDS" package, and choose New -> Java Class.

The following code shows the bean definition of our data source. Each driver should have a bean.

import org.springframework.beans.factory.annotation.Autowired; import org.springframework.boot.jdbc.DataSourceBuilder; import org.springframework.context.annotation.Bean; import org.springframework.context.annotation.Primary; import org.springframework.core.env.Environment; import javax.sql.DataSource; public class DriverManagerDataSource{ @Autowired private static Environment env; @Bean(name ="DynamicsCRM") @Primary public static DataSource DynamicsCRMDataSource() { DataSourceBuilder<?> dataSourceBuilder = DataSourceBuilder.create(); dataSourceBuilder.driverClassName("cdata.jdbc.dynamicscrm.DynamicsCRMDriver"); dataSourceBuilder.url("jdbc:dynamicscrm:User=myuseraccount;Password=mypassword;URL=https://myOrg.crm.dynamics.com/;CRM Version=CRM Online;"); return dataSourceBuilder.build(); } //@Override public void setEnvironment( final Environment environment) { env=environment; } }

Next, move the Dynamics CRM jar file to the Documents folder (see path in command below) - The idea is to have a path without any spaces for the jar file. Then, click the Maven icon (top right corner of IntelliJ) and click "Execute Maven Goal." Now, run the following command:

mvn install:install-file "-Dfile=C:\Program Files\CData[product_name] ####\lib\cdata.jdbc.dynamicscrm.jar" -DgroupId=org.cdata.connectors -DartifactId=cdata-dynamicscrm-connector -Dversion=23 -Dpackaging=jar

Follow either of the given steps to run this command:

  1. The "-Dfile location" can be kept as the default installation path of the CData JDBC Driver. Make sure to keep the path in quotations in this case. Also, change the year and "Dversion" based on the current version of the driver being used.
  2. As mentioned earlier in the article, in case you relocate the jar file to the Documents folder, make sure to modify the path in the provided command. In such instances, avoid enclosing the Dfile location in quotations and edit "Dversion" based on the current version of the driver being used.

After pressing enter, we see the following output:

Testing the Connection

The last step is testing the connection. Create a new Java class following the format (e.g., "MDSApplication"). You have the flexibility to select any name for the application class. We call the data source in the main method of MDSApplication.java:

import org.springframework.boot.SpringApplication; import org.springframework.boot.autoconfigure.SpringBootApplication; import org.springframework.boot.autoconfigure.jdbc.DataSourceAutoConfiguration; import java.sql.Connection; import java.sql.SQLException; import static com.example.demo.DriverManagerDataSources.DynamicsCRMDataSource; @SpringBootApplication(exclude = {DataSourceAutoConfiguration.class}) public class MDSApplication { //remove the comment on the line below public static void main (){ SpringApplication.run(DemoApplication.class, args); Connection conn = DynamicsCRMDataSource().getConnection(); System.out.println("Catalog: "+ conn.getCatalog()); } }

The output generated should look like this:
