Question

我正在使用Spring 4.0.3.RELEASE.My项目工作正常，但添加 jackson-mapper-asl 之后，为了处理这样的错误由此请求只能根据请求“接受”标题生成具有不可接受的特征的响应，更新项目（之前清理和清理TomCat工作目录），更新后的部署组合中我添加Maven依赖项并且我经常收到错误 java.lang.ClassNotFoundException 。我的pom.xml

这是我的部署组合和项目结构 Deployment Assembley Project structure

Answer 1

You need to update your pom.xml and  use 1.8.5 version of  jackson-mapper-asl

Example

<dependency>
    <groupId>org.codehaus.jackson</groupId>
    <artifactId>jackson-mapper-asl</artifactId>
    <version>1.8.5</version>
</dependency>

添加jackson-mapper-asl会导致java.lang.ClassNotFoundException
