java - 在将 XML 映射到 Java Bean 方面需要帮助

Question

我有一个如下的 XML ...

<employeeId>323</employeeId>
<name>Samuel DCosta</name>
<department>
    <departmentId>2</departmentId>
    <name>Accounts</name>

我想将这些值映射到我拥有的 Java Bean ....XML 中的键与 bean 中成员的名称匹配......有人告诉我是否有一种简单的方法请在 Java 中执行此操作......欢迎使用工具或组件......

部门....

import java.io.Serializable;

public class Department implements Serializable
{
private Long departmentId;

private String name;

@Override
public String toString()
{
    return "Department [departmentId=" + departmentId + ", name=" + name + "]";
}

public Long getDepartmentId()
{
    return departmentId;
}

public void setDepartmentId(Long departmentId)
{
    this.departmentId = departmentId;
}

public String getName()
{
    return name;
}

public void setName(String name)
{
    this.name = name;
}
}

员工......

import java.io.Serializable;

public class Employee implements Serializable
{
private Long employeeId;

private String name;

private Department department;

private Integer salary;

@Override
public String toString()
{
    return "Employee [employeeId=" + employeeId + ", name=" + name + ", department=" + department + ", salary="
            + salary + "]";
}

public Long getEmployeeId()
{
    return employeeId;
}

public void setEmployeeId(Long employeeId)
{
    this.employeeId = employeeId;
}

public String getName()
{
    return name;
}

public void setName(String name)
{
    this.name = name;
}

public Department getDepartment()
{
    return department;
}

public void setDepartment(Department department)
{
    this.department = department;
}

public Integer getSalary()
{
    return salary;
}

public void setSalary(Integer salary)
{
    this.salary = salary;
}
}

您可以使用 JAX-B

Java Architecture for XML Binding (JAXB) provides a fast and convenient way to bind XML schemas and Java representations, making it easy for Java developers to incorporate XML data and processing functions in Java applications. As part of this process, JAXB provides methods for unmarshalling (reading) XML instance documents into Java content trees, and then marshalling (writing) Java content trees back into XML instance documents. JAXB also provides a way to generate XML schema from Java objects
