我正在使用Maven从事Java Web Service,具体取决于另一个java项目。我将调用Web服务项目(项目2)和依赖项目(项目1)
所以我有一个"项目1"这个项目使用" com.fasterxml.jackson.datatype.joda.JodaModule"罐。 "项目1"有这种依赖。

现在我需要使用&#34;项目1&#34;在&#34;项目2&#34;。所以我写了这段代码
@Override
protected void doPost(HttpServletRequest request, HttpServletResponse response)
throws ServletException, IOException {
ObjectMapper mapper = new ObjectMapper();
mapper.setDateFormat(new ISO8601DateFormat());
mapper.setSerializationInclusion(JsonInclude.Include.ALWAYS);
JodaModule module = new JodaModule();
mapper.registerModule(module);
}
但是当我从客户端拨打邮件时。它给了我这个错误。

注意:我在Maven Java Project而不是Maven Web Java Project中尝试相同的代码,它在Maven java项目中工作。
public class test {
public static void main(String[] args) {
ObjectMapper mapper = new ObjectMapper();
mapper.setDateFormat(new ISO8601DateFormat());
mapper.setSerializationInclusion(JsonInclude.Include.ALWAYS);
JodaModule module = new JodaModule();
mapper.registerModule(module);
}
}
编辑1:
我正在研究glassfish 4.1,当我将服务器更改为tomcat时,它可以工作。所以我认为glassfish中存在冲突罐子。但直到现在我还不知道如何解决这场冲突。
答案 0 :(得分:17)
这是由于jackson libs和joda之间的依赖性不匹配造成的。当仅使用原始Maven模块时,它正在为你工作,因为它将所有jackson库声明为2.6.2,这是正确的。你的封闭webapp肯定使用另一个杰克逊版本作为直接或传递依赖。这会导致类似路径上存在不兼容的jar。
验证:只需检查您的WEB-INF / lib并查找与jackson相关的所有库。你会发现非2.6.2版本的。
要修复:您需要决定是否可以在网络应用上升级到新版本。然后相应地配置Maven依赖项。
答案 1 :(得分:2)
它看起来像是依赖冲突。确保两个项目都加载相同的joda-time(及其依赖项)版本。
您可以通过在命令行中运行mvn dependency:tree
或在使用POM编辑器打开pom.xml时查看依赖关系层次结构面板来查看依赖关系树蚀。
