使用Java代码stream().filter()对多个字段属性过滤筛选，并返回所有字段

背景介绍：

在ESB项目迁移中，遇到过滤数据的需求，这里使用Java代码stream().filter()实现。

解决方案：

参考代码如下：

public Student(String name, String age, String sex) {
            this.name = name;
            this.age = age;
            this.sex = sex;
        }

        public String getName() {
            return name;
        }

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

        public String getAge() {
            return age;
        }

        public void setAge(String age) {
            this.age = age;
        }

        public String getSex() {
            return sex;
        }

        public void setSex(String sex) {
            this.sex = sex;
        }

        @Override
        public String toString() {
            return "Student{" + "name='" + name + '\'' + ", age='" + age + '\'' + ", sex='" + sex + '\'' + '}';
        }

主函数：

public static void main(String[] args) {
            Student student1 = new Student("11", "11", "0");
            Student student2 = new Student("11", "22", "1");
            Student student3 = new Student("11", "22", "0");
            Student student4 = new Student("11", "33", "1");
            Student student5 = new Student("22", "33", "0");
            List<Student> students = new ArrayList();
            students.add(student1);
            students.add(student2);
            students.add(student3);
            students.add(student4);
            students.add(student5);
            System.out.println("--------------------对象去重-----------------------");
            List<Student> collect = students.stream().distinct().collect(toList());
            for (Student student : collect) {
                System.out.println(student);
            }
            System.out.println("-------------------根据多个字段去重--------------------------");
            ArrayList<Student> collect1 = students.stream().collect(Collectors.collectingAndThen(Collectors.toCollection(() -> new TreeSet<>(Comparator.comparing(student -> student.getName() + student.getAge()))), ArrayList::new));
            for (Student student : collect1) {
                System.out.println(student);
            }
            System.out.println("-------------------根据多个字段条件过滤筛选--------------------------");
            List<Student> filterCollect = students.stream().filter(s -> Objects.equals(s.getName(), "11") && Objects.equals(s.getSex(), "0")).collect(Collectors.toList());
            for (Student student : filterCollect) {
                System.out.println(student);
            }

执行结果：
