Configuration file introduction

WEB-INF stores server information and configuration information. The structure of the folder is as follows:

including:

backup folder: the backup of the server configuration information. See Backup and restore server configuration.
config folder: configuration files, including caching schemes for Bing Maps, Tianditu, Cloud service, etc.
iserver-datastores-manifests: stores the configuration infos of data in data catalog service.
lib folder: stores the jar files that SuperMap iServer depends on.
worker-lib: stores the servlet-api.jar which is used to starting Workers nodes.

The main contents of each configuration file are as follows:

Among them, <isSecurityEnabled>is used to enable or disable the security control; <tokenKey> is used to set the share key of Token; <cacheInfoToMemory> is used to set whether save all user info in memory,and get the information from memory.The default is true,which represents saving all user info in memory.If there is a large number of users,you are advised to set it to false,which represents the user info can be get from database in real time,because there will need to a large amount of SQL query,which can cause the performance to slow down；<passwordProtectedSetting> is used to protect password from cracking violently, specific parameters include:

<passwordDiffCount>: New input password can not be set the same as any previous setting for last N times. Default value is 5.
<userPasswordErrorCounterSetting>: including subnodes, <passwordErrorProtectEnable>, <allowFailCountPerPeriod>, and <lockedTime>. <passwordErrorProtectEnable> is used to enable or disable password anti-voilence crack setting. <allowFailCountPerPeriod>, default value is 5 times, indicates number of consecutive failures allowed in the time peroid (<periodLength>, default value is 6000000 miliseconds, or 10 minutes). <lockTime> indicates the automatic lock time. The unit is miliseconds, default 1200000, or 20 minutes.

<storageSetting> is used to set the storage location of security information, including <type> field and <connInfo> field. <type> is used to set the database storage type, and currently supports SQLITE, MYSQL. <connInfo> is used to configure the connection information of database. Take the MYSQL database as an example, the connection information specific parameters include:

<driverClass>: database connection driver class, com.mysql.jdbc.Driver
<jdbcUrl>: the URL connection form for connecting database driver is jdbc:mysql://{ip}:{port}/{database}?useUnicode=true&characterEncoding=UTF-8. {ip} indicates the IP address of the machine where the MYSQL is located. {port} indicates the service port of MYSQL, and the default is 3306. {database} is the database name. You can configure these parameters according to the actual enviroment of MYSQL you installed.
<username>: user name, the user who has access to the database {database}.
<password>: the user's password.
<initialPoolSize>: the connection pool size of initializing, that is, the number of initial connections. The default value is 5.
<maxPoolSize>: the maximum number of active connections provided by the connection pool at the same time. You can set this value based on the performance of the MySQL server, which defaults to up to 30 active connections.
<minPoolSize>: the minimum number of active connections provided by the connection pool at the same time. Default value is 5.
<maxIdleTime>: idle connection waiting time. That is, when the current connection is idle, the time that can be retained in milliseconds. If the time is not operated out of maxIdleTime, the current connection is automatically closed. The default value is 3000. If set to 0, the idle connection is always retained.
<maxWait>: the waiting miliseconds for an abnormal connection. When the connection is not restored during this time period, the current connection is automatically closed. The default value is 300000.
<useStoredAdmin>: for the case where the initial administrator (for example, admin1) has been stored in the database. The default value is false. If it is false, the current initial administrator (admin2) will be used; If it is true, the administrator (admin1) which is stored in the database will be used, not the current one (admin2).

<Session> is used to specify the storage location of the session information, including the Redis database connection pool configuration. Specific parameters are as follows:

<type>: database type.
<host>: the IP address of the machine where the Redis dababase is located.
<port>: the service port of Redis dababase.
<MaxActive>: the maximum number of active connections provided by the connection pool at the same time.
<MaxIdle>: Maximum number of free connections.
<MaxWait>: the maximum waiting time in milliseconds for a available connection. After the timeout, an exception will be throwed.
<Timeout>: The time of the client is in an idle state after it is connected to the database. After the timeout, the connection will be disconnected.
<TestOnBorrow>: When using a connection, it detects whether the connection is available; true means the resulting connection is available.

3. <hosts> element

The <host> element is used to configure the host of SuperMap iServer. There can be multiple <host> elements. A host example is as follows:

<host port="8090" type="webapp" uriBase="/services">
        <interface-type>com.supermap.services.wms.WMSServlet</interface-type>
        <interface-type>com.supermap.services.rest.RestServlet</interface-type>
        <interface-type>com.supermap.services.wfs.WFSServlet</interface-type>
        <interface-type>com.supermap.services.wmts.WMTSServlet</interface-type>
</host>

The subnode of <host>, <interface-type>, indicates the type of service contained in the service host; The attributes of <host> have the following meanings:

port, the port number of the service host. The service through which the user accesses the service host, matches the port number of the servlet container, and synchronizes with the port number of the servlet container when accessing the SuperMap iServer service.
type, the type of service host. "webapp" means that this is a Web service; It can also be set to rmi, soap, indicateing other host type.
uriBase, the root path of the service host. It is counted from the root directory of the servlet.

4. <clustering> element

Including applications such as cluster configuration.. For more information about the elements of cluster subnodes, refer to using the configuration file to manage cluster which is under the cluster configuration topic .

5. <harLog> element

It used to configure the service access logs, such as whether to enable the service access log, the file name of service access log, the settings of service URI address:

<enabled>: set whether to enable the service access log, the default is false.
<name>: the name of the service access log. The default name is iServerHTTPArchive
<monitorURLs>: the service URL address of SuperMap iServer to be monitored.

6. <queryFilter> element

It is used in the SQL query filter configuration to prevent SQL injection. SQL injection means to insert the strings that illegal or go against the user wishes into SQL query expression in data or map SQL query.

<enabled>: set whether to enable SQL query filtering, the default is true.
<filterString>: sets the SQL query filter string, supports any string (data manipulation language (DML), expression, wildcard, special characters, etc.), separated by semicolons, such as: <filterString>delete;SMID=.</filterString> . When users use data or map SQL query, if there is delete or SMID=arbitrary value in the expression, the system will regard the query expression as illegal and return 400 parameter exception, which protect the security of user data. If you do not set the SQL query filter string, The semicolon in the SQL query expression will be shielded by the system.

7. <repository> element

Used to set the storage location for temporary resources. For more information, please refer to: Temporary Resource Lifecycle.

8. <relayService> element

The relay service configuration for iEdge is only used in iEdge products.

<enabled>: Whether to enable relay service.
<IsLocalPriority>: whether to use the local service for the same name service. If true, the local service is used first, and the service of the same name in the relay server will be hidden. If false, the relay service will be used first, and the local service will be hidden.
<remoteServices>: The list of remote service in the relay service, such as: http://<server>:<ip>/iserver/services.
<updateInterval>: The interval at which the relay service is dynamically updated. If the remote service list has changed, the relay service dynamically updates according to this interval. In milliseconds (ms), the default is 60000ms.

9.<license> element
