导入maven项目后报错 找不到类

Question

引入了一个maven项目
springmvc内容：
 <!--自定义参数绑定组件-->
    <bean id="conversionService" class="org.springframework.format.support.FormattingConversionServiceFactoryBean">
        <!-- 转换器 -->
        <property name="converters">
            <set>
                <!-- 日期类型转换 -->
                <bean class="cn.goodym.controller.converter.CustomDateConverter"/>
            </set>
        </property>
    </bean>
后报错：
Multiple annotations found at this line:
- Class 'org.springframework.format.support.FormattingConversionServiceFactoryBean' not found [config set: 
 Examination_System/web-context]
- Class 'org.springframework.format.support.FormattingConversionServiceFactoryBean' not found

Answer 1

我更改了版本以后没有在报错但是<context:component-scan base-package="cn.goodym.controller"/>这一行报错
Multiple annotations found at this line:
- cvc-complex-type.2.4.c: The matching wildcard is strict, but no declaration can be found for element 'context:component-scan'.
- schema_reference.4: Failed to read schema document 'http://www.springframework.org/schema/context/spring-context.xsd', 
 because 1) could not find the document; 2) the document could not be read; 3) the root element of the document is not <xsd:schema>.

Answer 2

右键单击项目 -- Maven - update project 不行的话更改一下setting.xml配置文件 再update project

Answer 3

可以Run As test
然后看报错信息有下载的包在本地的位置,找到那个下载不完全的包,删掉
重新run as install一下试试

Answer 4

没下载好呗，你看下import包有没有报找不到

Answer 5

可能是你之前的maven包存在冲突了，找出来删掉，从新加载就行了

Answer 6

先去maven文件夹里面删掉然后重新install试试？我也是新手

Answer 7

1.在maven目录/conf/setting.xml修改源为阿里的源
2.找到报错的是哪个包，去maven仓库检查，如果后缀是.lastPXXX，则将其全部删除。
3.重新编译你的项目。

Answer 8

删掉本地仓库里面的jar包，重新import一次，或者直接在仓库里面看看能不能找到这个包，找不到就去私服看有没有，私服有的话就看settings是否有问题。私服有本地有就看版本对不对
