This brief article has showcased the basics of two distinct ways to use Constructor-Based Dependency Injection using the Spring framework. The full implementation of this article can be found over on GitHub.Mac
一:这里先说一下DI(Dependency Injection)依赖注入有种表现形式:一种是CI(Constructor Injection)构造方法注入,另一种是SI(Set Injection) set 注入。这篇随笔讲的是第一种构造方法注入(Constructor Injection). 其实DI(Dependency Injection)依赖注入你不妨反过来读:注入依赖也就是把"依赖"注入到一个对象中去。那么何...
2. Constructor-Based Dependency Injection A good way to wire dependencies in Spring using constructor-based Dependency Injection. This approach forces us to explicitly pass component’s dependencies to a constructor. As opposed toField-Based Dependency Injection, it also provides a number of advantages...

For configuring spring in your eclipse ide please refer hello world example Dependency Injection via Constructor 1.Country.java:...
In the Spring Framework, the Dependency Injection comes in three types. These are Field Injection, Setter Injection and Constructor Injection. You can use any of them, resulting in the same outcome. However, there are a few differences based on ease, readability, coding standards or better codin...
Spring Team recommends "Always use constructor based dependency injection in your beans. Always use assertions for mandatory dependencies". 翻译: Spring建议”总是在您的bean中使用构造函数建立依赖注入。总是使用断言强制依赖”。 这段代码警告原来的写法是: ...

In some scenarios, we may need to inject an array of strings to an object.Consider the example where Person has hobbiesIn this case, we can use Array of Strings which stores the hobbies Let us see the same in spring through Constructor Dependency Injection...
