SPRING-SPRINGMVC Build (iii) SPRINGMVC add support for static resource access and support for Fastjson

1. Add a visit to a static resource. Js/.img/.css

There are 3 types of methods:

1, change the path of the Springmvc Dispatherservlet urlpattern to "/*.do".

2. Add <mvc:default-servlet-handler>, and at the same time add the default mapping type in Web. xml to allow SPRINGMVC to identify those that can be released.

Add:<mvc:default-servlet-handler/> in the context of SPRINGMVC

In Web. xml
<servlet-mapping>
<servlet-name>default</servlet-name>

 <url-pattern>*.js</url-pattern>

</servlet-mapping>

<servlet-mapping>
 <servlet-name>default</servlet-name>
 <url-pattern>*.ico</url-pattern>
</servlet-mapping>

3. Using <mvc:resources >

<mvc:resources mapping= "" location= ""/>

2,springmvc adding support for Fastjson

Springmvc's httpmessageconverter is the use of mappingjackjson2httpmessageconverter, but is now generally used Ali's Fastjson, So I'm going to replace Fastjsonhttpmessageconverter.

    <!--enhancement Annotations-    <mvc:annotation-driven>        <mvc:message-converters register-defaults= "false" >            <bean class= "Com.alibaba.fastjson.support.spring.FastJsonHttpMessageConverter"                  id= " Fastjsonhttpmessageconverter ">                <property name=" Supportedmediatypes ">                    <list>                        < value>application/json;charset=utf-8</value>                    </list>                </property>                <!--< Property Name= "Serializerfeature" >-->                <!--This place with this function, you can configure some things, such as the format of the time, null output "" and so on                . <!--</property>-->            </bean>        </mvc:message-converters>    </MVC: Annotation-driven>

　　

Add Fastjson maven dependencies to the Pom file

      <!--Https://mvnrepository.com/artifact/com.alibaba/fastjson--      <dependency>          <groupid >com.alibaba</groupId>          <artifactId>fastjson</artifactId>          <version>1.2.47 </version>      </dependency>
