If you use spring.net as your IOC container, be sure to pay attention to this problem. --spring.net currently does not support access qualifiers of getter and setter. We usually use the setter attribute for dependency injection, for example, public Class. { # Region B Private B; Public B { Get {return B ;} Set {B = value ;} } # Endregion } Public Class B{} For t

used through reflection.@ Resource Assembly Sequence . @ PostConstruct (JSR-250)Add the annotation @ PostConstruct to the method. This method will be executed by the Spring container after Bean initialization (Note: Bean initialization includes instantiating Bean, and assemble Bean attributes (dependency injection )).A typical application scenario is that when you need to inject an attribute defined in the

If it is a forced dependency, then use the constructor injection and, if it is an optional dependency, use the Set method. Spring encourages constructor injection to ensure that a dependency is not null.Since you can mix constructor-based and setter-based DI, it's a good rule of thumb to use constructors for mandatory Dependencies and Setter methods or configurat

With the introduction of spring annotations, more and more developers began to use annotations, this article will explain the mechanism of the annotations in series, do not seek thorough, but to string up the spring beans annotation of the pearl, show to everyone.1. Common annotations for Spring beans:Public @interface

package cn.com.xf; public class User { private String name; private int age; private String remark; //Getter/setter method of omitting properties @Override public String toString () { return "User [n Ame= "+ name +", age= "+ Age +", remark= "+ remark +"] "; Packagecn.com.xf; Public classUserutil {Privateuser User; PublicUser GetUser () {returnuser; } Public voidsetUser (user

has already injected a value for the property, Spring still considers that it has not executed the injection and throws an exception. In addition, Spring only executes the injection through Setter, but has no requirements on the injection value. Even if the injected None -- the dependency check is not performed by default. You can use the default-dependency-

To allow null values, set the required attribute to false, for example: @ Autowired (required = false ). if you want to use name assembly, you can use the @ Qualifier annotation.

If type is specified, an exception will be thrown if a unique bean of type matching is found in the context for assembly and no or multiple beans can be found.4. If neither name nor type is specified, the system automatically performs the Assembly in byName mode. If no match exists, the system returns to an original type
