javaweb project get access UOB credit card records

1, download the official UOB network equipment sdk_java64, address: https: //www.dahuatech.com/service/downloadlists/836.html

2, there are examples of SDK, to make use of UOB packaged things, acquiring an access card used in recording the following java class:
    COM / NETSDK / lib
        NetSDKLib.java
        ToolKits.java
        in Utils.java
    COM / NETSDK / Demo / Module1
        LoginModule.java
   
    I thought com.netsdk.demo.module.GateModule.java which will have ready access to records of access card implementation, but unfortunately did not. Than painted gourd dipper, wrote a.
   
3, the introduction libs / jna.jar in their spring boot project.

    <dependency>
      <groupId>com.dahua</groupId>
      <artifactId>jna</artifactId>
      <version>1.0</version>
      <scope>system</scope>
      <systemPath>${project.basedir}/lib/jna.jar</systemPath>
    </dependency>

 

    dll file in the libs / win64 UOB libraries, run-time to read, there are ways to read in the Utils.java,
    can follow a path which is stored in its own path corresponds to the item. My project is spring boot, put on the same level libs file src file to start the project folder.
    Web-len
        -src
        -libs
            -win64

4, UOB pit: Notes document and class, are stated access credit card records can be retrieved through the period, but some do not support access control equipment, will give you all the all the records;
    note LoginModule initialization method init, for javaweb project is concerned, when the service starts, the initialization time on the line, followed by a direct call to login, logout methods can be,
    do not call the init method multiple times, so java memory will be ringing off the hook, so I started doing that the (depressed) ...... there is a credit card records of the time is not Beijing, but the district 0:00
    time, so they wanted to get to plus 8 hours is Beijing time.

5, when using maven package, if missed jna.jar, on the spring-boot-maven-plugin in pom.xml plus <includeSystemScope> true </ includeSystemScope>
    follows:
<plugins>
  <plugin>
    <the groupId > org.springframework.boot </ the groupId>
    <the artifactId> Boot-Spring-Maven-plugin </ the artifactId>
    <Configuration>
      <includeSystemScope> to true </ includeSystemScope>
    </ Configuration>
  </ plugin>
</ plugins>
