Spring mvc Junit单元测试异常解决

编程语言 2018-06-08 22:07:18 阅读次数: 7

今天在做单元测试的时候出现了各种异常情况。可是项目通过Tomcat容器发布运行没有任何问题，项目框架是spring 4.3.3 + mybatis。


问题一:

问题描述：是由于项目中使用了property-placeholder 特性，项目部署发布都一切正常，可是在使用junit的时候却出了问题。


解决办法：将上述方式改为如下

<bean id="propertyPlaceHolderConfigurer"
          class="org.springframework.beans.factory.config.PropertyPlaceholderConfigurer">
        <property name="locations">
            <list>
                <value>classpath:application.properties</value>
                <value>classpath:xxxxConfig.properties</value>
            </list>
        </property>
    </bean>

问题解决：在项目中添加如下依赖

<dependency>
   <groupId>org.apache.tomcat.embed</groupId>
   <artifactId>tomcat-embed-websocket</artifactId>
   <version>8.5.28</version>
</dependency>

注意：我使用的spring 4.3.3，如果tomcat-embed-websocket版本为8.5.15还是有问题，而使用8.5.28就完美解决。

问题描述：这是由于系统spring配置文件中使用了静态资源配置

问题解决：将静态资源的配置注释掉即可
