根据下面的xml数据生成springboot接收xml数据的实体类,要求实体类的属性可以再外部访问 <?xml version="1.0" encoding="UTF-8"?> <bookstore> <book category="COOKING"> <title lang="en">Everyday Italian</title> <author>Giada De Laurentiis</author> <year>2005</year> <price>30.00</price> </book> <book category="CHILDREN"> <title lang="en">Harry Potter</title> <author>J K. Rowling</author> <year>2005</year> <price>29.99</price> </book> <book category="WEB"> <title lang="en">XQuery Kick Start</title> <author>James McGovern</author> <author>Per Bothner</author> <author>Kurt Cagle</author> <author>James Linn</author> <author>Vaidyanathan Nagarajan</author> <year>2003</year> <price>49.99</price> </book> </bookstore>

生成实体类代码如下：

@XmlRootElement(name = "bookstore")
public class Bookstore {
  @XmlElement(name = "book")
  private List<Book> bookList;

  public static class Book {
    @XmlAttribute
    private String category;
    @XmlElement(name = "title")
    private String title;
    @XmlElement(name = "author")
    private String author;
    @XmlElement(name = "year")
    private String year;
    @XmlElement(name = "price")
    private String price;
  }
}

这样，就可以使用`bookList`访问每本书的信息了。

解释这几段代码<?xml version="1.0" encoding="UTF-8"?> <!DOCTYPE mapper PUBLIC "-//mybatis.org//DTD Mapper 3.0//EN" "http://mybatis.org/dtd/mybatis-3-mapper.dtd"> <mapper namespace="com.weather.project.mapper.ChartDataMapper"> </mapper> <?xml version="1.0" encoding="UTF-8"?> <!DOCTYPE mapper PUBLIC "-//mybatis.org//DTD Mapper 3.0//EN" "http://mybatis.org/dtd/mybatis-3-mapper.dtd"> <mapper namespace="com.weather.project.mapper.UserMapper"> </mapper> @Mapper public interface ChartDataMapper extends BaseMapper<ChartData> {} @Mapper public interface UserMapper extends BaseMapper<User> {} @Service public class ChartDataServiceImpl extends ServiceImpl<ChartDataMapper, ChartData> implements ChartDataService {} @Service public class UserServiceImpl extends ServiceImpl<UserMapper, User> implements UserService {} public interface ChartDataService extends IService<ChartData> {} public interface UserService extends IService<User> {}

这是MyBatis的代码片段，用于定义数据访问对象与实体类之间的映射关系。其中，第一个代码片段定义了一个名为 "com.weather.project.mapper.ChartDataMapper" 的MyBatis Mapper接口，与 ChartData 实体类相关联；第二个代码片段定义了一个名为 "com.weather.project.mapper.UserMapper" 的Mapper接口，与 User 实体类相关联。@Mapper 注解表示这些接口是MyBatis的Mapper接口；@Service 注解表示这些类是Spring的Service类，用于提供业务逻辑。最后，这些业务逻辑接口继承自IService接口，用于提供常用的增删改查操作。

<?xml version="1.0" encoding="UTF-8" ?> <!DOCTYPE configuration PUBLIC "-//mybatis.org//DTD Config 3.0//EN" "http://mybatis.org/dtd/mybatis-3-config.dtd"> <configuration> <properties resource="db.properties"/> <settings> <setting name="cacheEnabled" value="true"/> </settings> <typeAliases> <package name="com.itheima.pojo" /> </typeAliases> <environments default="development"> <environment id="development"> <transactionManager type="JDBC"/> <dataSource type="POOLED"> <property name="driver" value="${mysql.driver}"/> <property name="url" value="${mysql.url}"/> <property name="username" value="${mysql.username}"/> <property name="password" value="${mysql.password}"/> </dataSource> </environment> </environments> <mappers> <mapper resource="StudentMapper.xml"/> <!--任务6：声明MyClassMapper【5分】--> </mappers>

这是一个 MyBatis 的配置文件，其中包含了数据库连接信息和一些 MyBatis 的配置项，例如开启缓存等。此外，还声明了一个名为 StudentMapper.xml 的 XML 映射文件，用于映射 SQL 语句和 Java 对象之间的关系。在任务6中，需要声明一个名为 MyClassMapper.xml 的 XML 映射文件，用于映射另一个表或实体类的 SQL 语句和 Java 对象之间的关系。
