Answer 1

您似乎正在使用Jersey 1.x（JAX-RS 1.1实现）和JAX-RS 2.0 API。在您的应用程序中，切换到Jersey 2（推荐）或用JAX-RS 1.1 API jar替换JAX-RS 2.0 API jar（它已经是jersey-common的一部分，因此删除2.0 API应该足够了。）

Answer 2

你有maven依赖问题，删除所有依赖项，特别是容器jersey依赖项并添加这些：

<dependency>
<groupId>com.sun.jersey</groupId>
<artifactId>jersey-server</artifactId>
<version>1.9</version>
</dependency>
<dependency>
<groupId>com.sun.jersey.contribs</groupId>
<artifactId>jersey-multipart</artifactId>
<version>1.9</version>
</dependency>
<dependency>
<groupId>com.fasterxml.jackson.jaxrs</groupId>
<artifactId>jackson-jaxrs-json-provider</artifactId>
<version>2.5.1</version>
</dependency>

Answer 3

我需要针对该问题的更具体答案，因此我向maven添加了以下插件：

<plugin>
  <groupId>org.apache.maven.plugins</groupId>
  <artifactId>maven-enforcer-plugin</artifactId>
  <version>3.0.0-M3</version>
  <executions>
    <execution>
      <id>enforce</id>
      <configuration>
        <rules>
          <dependencyConvergence/>
        </rules>
      </configuration>
      <goals>
        <goal>enforce</goal>
      </goals>
    </execution>
  </executions>
</plugin>

上面显示了我所有的依赖项冲突，因此我设法解决了上述问题之外的更多问题，并使我的依赖关系树保持整洁。

该插件在调用时运行：

mvn clean install

并向您显示以下警告：

[WARNING] 
Dependency convergence error for com.fasterxml.jackson.core:jackson-core:2.8.10 paths to dependency are:
+-com.omilia:partners:5.4.0-RC-3
  +-org.glassfish.jersey.media:jersey-media-json-jackson:2.27
    +-com.fasterxml.jackson.module:jackson-module-jaxb-annotations:2.8.10
      +-com.fasterxml.jackson.core:jackson-core:2.8.10
and
+-com.omilia:partners:5.4.0-RC-3
  +-com.fasterxml.jackson.core:jackson-databind:2.9.6
    +-com.fasterxml.jackson.core:jackson-core:2.9.6

随后，当在pom中引用依赖项时，您可以排除特定的程序包：

<exclusion>
  <groupId>com.fasterxml.jackson.core</groupId>
  <artifactId>jackson-core</artifactId>
</exclusion>
