Configuring service providers through XML file

Service providers provide functions for service components, which are the sources of the service logic processing for the service components. SuperMap iServer allows users to customize service providers (iServer configuration file). The configuration of the service provider includes workspace path, cache path, cache access path, etc. Different service provider types have different configuration items.

The service provider is configured on the node <provider/>. Table 1 Implementation and configuration of service provider shows the basic type, the implementation class, the configuration class, etc.

Presetting local workspace path

For service providers that use local workspace as data source, iServer also supports to preset workspace paths in environment variables and in system configuration files, besides the way that you can set the whole or relative data path directly in the XML configuration file.

If you have preset the data path, you can directly read the workspace data from the path when configuring the service provider through XML without having to write the full data path.

Presetting through environment variable

The specific operation is as follows:

1. Set the system environment variable for the workspace

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

2. Use the existing environment variable in the service provider configuration file

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

Presetting through iServer sytem configuration file

The specific operation is as follows:

1. Add the following configuration items for the workspace in the <properties> node of iserver-system.xml file. For configuration items, see: iServer Configuration file introduction

• <data1>E:/supermap/data/China.smwu</data1>
• Or: <datapath1>E:/supermap/data</datapath1>

2. Use the variables created in step 1 in the service provider configuration file

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

Note: If you set the workspace path in both of these ways, iServer preferentially uses the data set in the environment variable.
