本文整理了Java中javax.xml.bind.JAXB类的一些代码示例，展示了JAXB类的具体用法。这些代码示例主要来源于Github/Stackoverflow/Maven等平台，是从一些精选项目中提取出来的代码，具有较强的参考意义，能在一定程度帮忙到你。JAXB类的具体详情如下：
包路径：javax.xml.bind.JAXB
类名称：JAXB

JAXB介绍

[英]Class that defines convenience methods for common, simple use of JAXB.

Methods defined in this class are convenience methods that combine several basic operations in the JAXBContext, Unmarshaller, and Marshaller. They are designed to be the prefered methods for developers new to JAXB. They have the following characterstics:

  1. Generally speaking, the performance is not necessarily optimal. It is expected that people who need to write performance critical code will use the rest of the JAXB API directly.
  2. Errors that happen during the processing is wrapped into DataBindingException (which will have JAXBExceptionas its Throwable#getCause(). It is expected that people who prefer the checked exception would use the rest of the JAXB API directly.

In addition, the unmarshal methods have the following characteristic:

  1. Schema validation is not performed on the input XML. The processing will try to continue even if there are errors in the XML, as much as possible. Only as the last resort, this method fails with DataBindingException.

Similarly, the marshal methods have the following characteristic:

  1. The processing will try to continue even if the Java object tree does not meet the validity requirement. Only as the last resort, this method fails with DataBindingException.

All the methods on this class require non-null arguments to all parameters. The unmarshal methods either fail with an exception or return a non-null value.
[中]类，该类为JAXB的通用、简单使用定义方便的方法。
此类中定义的方法是方便的方法，它们结合了JAXBContext、Unmarshaller和Marshaller中的几个基本操作。它们被设计成JAXB新手的首选方法。它们具有以下特点：
1.一般来说，性能不一定是最优的。预计需要编写性能关键代码的人将直接使用JAXB API的其余部分。
1.处理过程中发生的错误被包装到DataBindingException中（这将使JaxBeException成为其可丢弃的#getCause（）。希望喜欢检查异常的人会直接使用JAXB API的其余部分。
此外，解组方法具有以下特点：
1.未对输入XML执行架构验证。即使XML中存在错误，处理也将尽可能继续。只有在万不得已的情况下，此方法才会因DataBindingException而失败。
类似地，封送处理方法具有以下特征：
1.即使Java对象树不满足有效性要求，处理仍将尝试继续。只有在万不得已的情况下，此方法才会因DataBindingException而失败。
此类上的所有方法都要求所有参数都具有非null参数。解组方法要么因异常而失败，要么返回非null值。
