Idea Open the project directory as follows

Modify the Java classes

In order to make Activiti compatible with the Damone database, some of its source code needs to be modified. Copy the relevant source code from Activiti to the project SRC directory, leaving the package path unchanged. The specific modifications are as follows:
In the org. Activiti. Engine. Impl. CFG. ProcessEngineConfigurationImpl, increase member variables.

    public static final String DATABASE_TYPE_DM = "dm";	// Add member variables to damont database! [image.png](https://p6-juejin.byteimg.com/tos-cn-i-k3u1fbpfcp/7f17e9e796a04e35a07a8c8165cef69d~tplv-k3u1fbpfcp-watermark.image)
    public static final String DATABASE_TYPE_H2 = "h2";
    public static final String DATABASE_TYPE_HSQL = "hsql";
    public static final String DATABASE_TYPE_MYSQL = "mysql";
    public static final String DATABASE_TYPE_ORACLE = "oracle";
    public static final String DATABASE_TYPE_POSTGRES = "postgres";
    public static final String DATABASE_TYPE_MSSQL = "mssql";
    public static final String DATABASE_TYPE_DB2 = "db2";

Modify org. Activiti. Engine. Impl. CFG. GetDefaultDatabaseTypeMappings ProcessEngineConfigurationImpl class () method

public static Properties getDefaultDatabaseTypeMappings(a) {

databaseTypeMappings.setProperty("DM DBMS", DATABASE_TYPE_DM); // Adapt dameng database, add modification
