| Difference between SpringMVC and Struts2 |

SrpingMVC |
Struts2 |
Advantage |
| frame entrance |
servlet based |
filter based |
|
| frame design ideas |
The controller is based on method-level interception, and the processor is designed as a single instance |
The controller is based on class-level interception, and the processor is designed to be multi-instance |
Due to the design itself, Struts2 can only be designed in multi-instance mode. Compared with springmvc's single-instance mode, Struts2 will consume more server memory. |
| Parameter passing |
Parameters are passed through method parameters |
Parameters are passed through member variables of the class |
Struts2 passes parameters through member variables, which makes the parameters thread unsafe and may cause concurrency problems. |
| Integrate with spring |
Same company as spring, seamless integration with spring |
Requires a modpack |
Springmvc can be more easily integrated with spring |
Execute the flow chart:
1. Processor Mapper
2. Processor adapter
2-in-1 configuration
<!-- Annotation-driven configuration, instead of separate configuration of mappers and adapters, and supports json response (recommended) --> <mvc:annotation-driven />
3. View resolvers
<!-- configure view resolver -->
<bean class="org.springframework.web.servlet.view.InternalResourceViewResolver">
<!-- Prefix of configuration view response -->
<property name="prefix" value="/WEB-INF/jsp/" />
<!-- Configuration view response suffix -->
<property name="suffix" value=".jsp" />
</bean>
以上被称为三大组件。
springmvc帮我们默认加载了这些组件：
