public class Test { public static void main(String[] args) { // 创建原始类的实例 MainClass original = new MainClass(); original.field1 = 1; original.field2 = "original";// 调用Copy构造函数 MainClass copy = new MainClass(original);// 打印复制后的字段值 System.out.println(copy.field1...
aIf a class does not explicitly declare any, the Java compiler automatically provides a no-argument constructor, called the default constructor . 如果类不明确地宣称其中任一, Java编译器自动地提供一个没有论据建设者,告诉缺省建设者。[translate]
Base Class Library The Mono platform provides a comprehensive set of classes that provide a solid foundation to build applications on. These classes are compatible with Microsoft's .NET Framework classes. Mono Class Library Mono also provides many classes that go above and beyond the Base Class Li...

so I would assume it would use an empty constructor. There is nothing particularly exotic about ApplicationEntity. It is define as a @Bean and has a chain of parent abstract classes marked as @MappedSuperclass. The top-most abstract class contains an @Id field named id, with a @GeneratedVa...
Applying other approaches like injecting ILogger via class constructor/property would require a big effort, including approach when each class would have OnLogMessage event. Thus LogContext approach is a negotiation between static Logger and Per-Instance Logger....
Using Spring Boot 3.0.1, I have the following POJO on which I wish to bind a certain property: public class TestProperties { private String prop1; private String prop2; public TestProperties(String prop1, String prop2) { this.prop1 = prop1; this.prop2 = prop2; } public String getPr...
