spring getter setter annotation

byname (see 2), and if there is no match, the fallback is matched to an original type (Userdao) and automatically assembled if matched; 3. @PostConstruct (JSR-250)With annotation @postconstruct on the method, this method is executed by the spring container after the bean is initialized (note: The bean initialization includes, instantiating the bean, and assembling the Bean's properties (Dependency injectio

today I've sorted out the annotations that spring uses: I hope I can help you! @ServiceFor labeling business layer components @ControllerUsed to label the control layer component (such as action in struts) @RepositoryUsed to annotate a data access component, the DAO component @ComponentAs a component, we can use this annotation to annotate when the component is not properly categorized. @AutowiredThe

automatically inject private member variables in the class. So when you use @Autowired for member variables, you can delete their getter and setter methods.Cases:public class Boss {@Autowired private car car; @Autowired Private Office office;}You can also use the @ autowired annotation for the set method and the constructor, equivalent to thepublic class Boss {p

Annotation management method 2 of Spring framework context uses annotation injection object attributes, springcontext First, it is the xml configuration file. NextIt is assumed that the dao class package com.swift;import org.springframework.stereotype.Component;@Component(value="dao")public class Dao { public String fun() { return "This is Dao's fun().

-dependency-check property on the Simple-Checks the original base type and collection type. Objects--Checks for complex types (except for types other than simple check types). All-check all types. Older versions are set in the configuration file using Dependency-check, with the disadvantage of coarse granularity. Use the @Required annotations provided by Spring2.0 to provide finer-grained control. @Required annotations can only be labeled on the

control. @Required annotations can only be labeled on the Setter method. Because the nature of dependency injection is to check that the Setter method is called, instead of actually checking to see if the property is assigned a value and what value is assigned. If the annotation is marked in a non-setxxxx () type method, it is ignored.In order for

corresponding Setter method for a given Bean is invoked at the time of instantiation. Instead of determining if the field already has a value. When Spring makes dependency checking, it only determines whether the attribute uses Setter injection. If a property does not use Setter injection, even if a value has been inj

, we need to instruct Spring IoC container to scan these classes labeled annotation, with the following methods: If you are using Genericxmlapplicationcontext to create the context, you need to add the following in the XML configuration file: Note, You can also use Annotationconfigapplicationcontext to create a context whose scan () method allows you to specify the package to scan;

Spring dependency Injection Use constructor Injection Use the setter Method for property Injection Use Field Injection (for annotation) In fact, there is another third case of injection, that is, field injection, which is generally used for annotation. Summary:Manual assembly or automatic assembly can be used to injec
