Configuring Service Provider through XML File

The service provider provide functions for the service components and are the source of the service components' business logic processing. SuperMap iServer provides the ability to customize service provider, This can be achieved by modifying the service configuration file iserver-services.xml(see the iServer Config File Description ). The configuration of service provider includes workspace path, cache path, cache access path, etc. The contents of configuration items are different for different provider types.

The specific configuration of service provider is performed in the < provider/> node, and the basic type, implementation class, and configuration class are shown in Table 1 Implementation and Configuration of Service Provider .

Preset local works pace path

For service provider whose data source is the local workspace , in addition to writing the full or relative data path directly in the XMLconfig file, iServer also supports preset workspace paths in environment variables and system configuration file.

If you preset a data path, when configuring service provider through XML, you can directly read the workspace data in the preset path without writing out the complete data path.

Preset via environment variable

The specific operation is as follows:

1. Specifies the path where the works pace or works pace path is located

• In the environment variables of the operating system, create a new environment variable and point to the workspace path, such as data1, idata2, point to: data1=E:/supermap/data/China400.smwu, data2=E:/supermap/data/Jingjin.sxwu.
• Or, create a new environment variable and point to the path of workspace, such as datapath1 and datapath2, pointing to the data path: datapath1=E:/supermap/data1, datapath2=E:/supermap/data2

2. Configure service provider and write the existing environment variables in the workspace path configuration item

• For ${iServerData1}, write: <workspacePath>${data1}<workspacePath>
• For ${iServerDataPath1}, write: <workspacePath>${datapath1}/China400.smwu<workspacePath>

Preset via system config file

The specific operation is as follows:

1. Add one or more variables representing the workspace path or path to the <properties> node in the system config file iserver-system.xml, as described in more detail in: iServer Config File Description

• For example: <data1>, and configuration information: <data1>E:/supermap/data/China.smwu</data1>
• For example: <datapath1>, and configuration information: <datapath1>E:/supermap/data</datapath1>

2. Configure service provider and write the existing environment variables in the workspace path configuration item

• For ${data1}, write: <workspacePath>${data1}<workspacePath>
• For ${datapath1}, write as follows: <workspacePath>${datapath1}/China400.smwu<workspacePath>

The above environment variables and system config file can be used to preset the local workspace data. However, if you set up the workspace using both of the above methods, iServer will prioritize using the data set in the environment variables.
