If you do not want to be overloaded, look for the LOG4J.CONFIGURATIONVM system variable and confirm that you have customized the configuration file path;3. Do not configure LOG4J.CONFIGURATIONVM system variables, order to find log4j.xml,log4j.properties under the root classpath To use a configuration file:

DI: Dependency Injection (Dependency injection), popular is a kind of XML configuration file, to the Sping container object initialization parameters. Also known as control reversal: inversion of the control (IoC)There are two main forms of dependency injection:|-: Dependency Injection based on construction method|-: Dependency Injection based on setter methodthe dependency injection based on the construction method can be divided into the following types:• Complex data types:• Simple data type:

Access domain for ndk development and ndk Development Java has two types of domains: instance domain and static domain. Each instance of a class has its own copy of the Instance domain, and all instances of a class share a static domain (based on Java SE ). JNI provides functions to access these two types of domains. The general steps are as follows: 1. Get the class through Object Reference 2. Obtain the domain ID through the class 3. Obtain the domain ID Next, we will proceed with the followi

Call Method for NDK development and call for ndk Development As described in the access domain of NDK development, Java methods are classified into two types: instance methods and static methods. JNI provides functions to access two types of methods. Let's take a look at how to access methods in Java in C.Our MainActivity has two methods: private String instanceMethod(){ return "Instance Method"; } private static String staticMethod(){ return "static Method"; } So how
