[置顶] XMLParser一个基于Dom4J的XML解析工具的使用

XMLParser介绍

compile 'lee.hua.xmlparse:xmlparse:2.2.2'

简单使用

@XmlBean(name = "BookNode")//XMLParser类注解,表示此类是一个XML标签，name表示输出的标签名
public class Book {
@XmlAttribute
public String name;//书名
@XmlAttribute
public Integer page;//页数
@XmlAttribute
public Float price;//价格
@XmlSingleNode(name = "Publisher",nodeType = Publisher.class)//XMLParser属性注解，表示一个子标签
public Publisher publishier;//出版商
@XmlListNode(name = "Author",nodeType = Author.class)//XMLParser属性注解，表示多个子标签
public List<Author> authors;//作者，多个
//省略无参构造 getter setter 和 toString 方法
}
@XmlBean(name = "Author")
public class Author {
@XmlAttribute
public String name;//作者名
//省略无参构造 getter setter 和 toString 方法
}
@XmlBean(name = "Publisher")
public class Publisher {
@XmlAttribute(name = "PUB") //XMLParser属性注解，name表示输出的属性名
public String pub;//出版社名称
//省略无参构造 getter setter 和 toString 方法
}

//生成XML文件
public void generate(){
//生成book数据
Book book = new Book();
book.setName("XMLParser解析");
book.setPage(55);
book.setPrice(37.5f);
book.setPublishier(new Publisher("中国花花出版社"));
List<Author> authors = new ArrayList<>();
for (int i = 0; i < 4; i++) {
Author author = new Author("author0"+i);
authors.add(author);
}
book.setAuthors(authors);
//设置注解扫描路径
XMLAPI.setXmlBeanScanPackage("com.lee");
//输出book对象
XMLAPI.writeObj2Xml(book,"/Users/lijie/Desktop/test.xml");
}

text.xml
<?xml version="1.0" encoding="UTF-8"?>
<BookNode name="XMLParser解析" page="55" price="37.5">
<Publisher PUB="中国花花出版社"/>
<Author name="author00"/>
<Author name="author01"/>
<Author name="author02"/>
<Author name="author03"/>
</BookNode>

public void readXML(){
//设置注解扫描路径
XMLAPI.setXmlBeanScanPackage("com.lee");
//调用readXML读取文件，并强转为Book对象
Book book = (Book) XMLAPI.readXML(new FileInputStream("/Users/lijie/Desktop/test.xml"));
//打印
System.out.println(book);
}

Book{
name='XMLParser解析', page=55, price=37.5,
publishier=Publisher{pub='中国花花出版社'},
Author{name='author00'},
Author{name='author01'},
Author{name='author02'},
Author{name='author03'}]
}

XMLParser使用详解

@XmlBean

@XmlAttribute

@XmlListNode

@XmlSingleNode

@Ignore

建模

<User name="test" age="18" marry="true" married="true">
<Books>
<Book name="java"/>
<Book name="android"/>
</Books>
<Phone number="110110110" type="home"/>
<Phone number="221221221" type="company"/>
</User>

/**
* 根据XML文件解析得来最外层User标签
*/
@XmlBean//标记为XML标签
public class User {
@XmlAttribute//标记为标签属性
public String name;
@XmlAttribute//标记为标签属性
public int age;
@XmlAttribute//标记为标签属性
public boolean marry;
@Ignore//忽略的标签属性
public boolean married = false;
@XmlSingleNode(name = "Books", nodeType = Books.class)//单个子节点 name=节点名字，nodeType=节点对应的JAVA类对象
public Books books;
@XmlListNode(name = "Phone", nodeType = Phone.class)//多个子节点
public List<Phone> phones;

//getter 和 setter
}

@XmlBean
public class Books {
@XmlListNode(name = "Book",nodeType = Book.class)
public List<Book> books;
//getter 和 setter
}

@XmlBean
public class Book {
@XmlAttribute
public String name;
//getter 和 setter
}

@XmlBean
public class Phone {
@XmlAttribute(name = "number")//解析属性为number的标签属性
public String phoneNum;
@XmlAttribute
public String type;
//getter 和 setter
}

读取XML文件

XMLAPI

@Test
public void testXML(){
//设置标签类（之前定义的User、Books等）的包路径
XMLAPI.changPackageName("lee.hua.databinding.xml_parse");
//调用XMLAPI.readXML()读取指定路径的XML文件
User userBean = (User) XMLAPI.readXML("/Users/lijie/Desktop/f.xml");
//打印user对象信息
System.out.println("XMLParser====="+ userBean);
}

XMLParser=====UserBean{name='test', age=18, marry=true, married=false,
books=Books{books=[Book{name='java'}, Book{name='android'}]},
phones=[Phone{phoneNum='110110110', type='home'},
Phone{phoneNum='221221221', type='company'}]}

生成XML文件

XMLAPI.writeObj2Xml(Object object,String ouputPath)

@Test
public void testXML(){
//读取f.xml文件，文件内容就是上面定义的User
XMLAPI.changPackageName("lee.hua.databinding.xml_parse");
File file = new File("/Users/lijie/Desktop/f.xml");
User userBean = (User) XMLAPI.readXML(new FileInputStream(file));
System.out.println("XMLParser====="+ userBean);
//为解析出的对象新加一本书，名称为XMLParser，输出到f2.xml
userBean.books.getBooks().add(new Book("XMLParser"));
XMLAPI.writeObj2Xml(userBean,"/Users/lijie/Desktop/f2.xml");
}

<?xml version="1.0" encoding="UTF-8"?>

<User name="test" age="18" marry="true">
<Books>
<Book name="java"/>
<Book name="android"/>
<Book name="XMLParser"/>
</Books>
<Phone number="110110110" type="home"/>
<Phone number="221221221" type="company"/>
</User>
