如何通过java反射为setter方法设置变量

有一些库的目标是减少创建 Junit 测试的时间和精力，例如Podam和Easytest。为简单起见，我喜欢在我的测试中使用 Podam。

1. 将 Podam 依赖添加到你的 pom.xml

   <dependency>
       <groupId>uk.co.jemos.podam</groupId>
       <artifactId>podam</artifactId>
       <version>7.0.5.RELEASE</version>
   </dependency>
   

2. 写你的豆子：

   2.1. 人.java

   public abstract class Peopple {
   
       private String name;
       private String mail;
       private List<String> phones;
   
       public String getName() {return name;}
       public void setName(String name) {this.name = name;}
       public String getMail() {return mail;}
       public void setMail(String mail) {this.mail = mail;}
       public List<String> getPhones() {return phones;}
       public void setPhones(List<String> phones) {this.phones = phones;}
   

   }

   2.2. 课程.java

   public class Course {
   
       private String code;
       private String name;
   
       public String getCode() {return code;}
       public void setCode(String code) {this.code = code;}
       public String getName() {return name;}
       public void setName(String name) {this.name = name;}
   
       @Override
       public String toString() {
           return return ReflectionToStringBuilder.toString(this, ToStringStyle.MULTI_LINE_STYLE);
     }
   }
   

   2.3. 学生.java

   public class Student extends Peopple {
   
       private Course course;
   
       public Course getCourse() {return course;}
       public void setCourse(Course course) {this.course = course;}
   
       @Override
       public String toString() {
           return return ReflectionToStringBuilder.toString(this, ToStringStyle.MULTI_LINE_STYLE);
       }
   }
   

3. 使用 Podam 填充豆子：

   public class PodamDataGenerator {
       public static void main(String[] args) {
   
           PodamFactory podamFactory = new PodamFactoryImpl();
           //Limit number of elements to collections fields
           podamFactory.getStrategy().setDefaultNumberOfCollectionElements(2);
           Student student = podamFactory.manufacturePojo(Student.class);
           System.out.println("Podam Pojo\n-----------\n " + student);
       }
   }
   

4. 输出

   Podam Pojo
   -----------
   Student[course=Course[code=Dr0zgS5ZKw,name=ZrGJ8xAcJQ],
           name=nB6zy558W5,mail=DuW6YyLgo3,phones=[Wlc7axk_A7, nQxDmUlukY]]
   

希望这可以帮助！
