spring getter setter annotation

remove the set and get methods. To achieve our goal of streamlining the program. You need to handle it like this: * Add the following content to applicationcontext. xml: Spring parses @ autowired through a beanpostprocessor, so to make @ autowired work, you must declare autowiredannotationbeanpostprocessor bean in the spring container in advance. * Modify the bean method in the original spirng container.

spring2.5 provides annotations (annotation-based)-based configuration, which we can use to complete injection dependencies. In Java code, you can use @Resource or @autowired annotations to line-inject. Although both @resource and @autowired can be used to complete the injection dependency, there is a difference between them. First Look at: @Resource By default is assembled by name, only if the bean that matches the name is not found to assemb

, there is no ambiguity and it is recommended. 2. Automatic assembly according to type (Bytype). The spring container may find multiple beans of the same type as the bean that needs to be injected, so there is ambiguity, and the spring container does not know which bean to inject, and throws an exception. 3. Automatic assembly according to the constructor (constructor). This approach is more complex and doe
