在Spring MVC控制器上接收JSON并反序列化为对象列表

这是对我有用的代码。关键是您需要一个包装器类。

public class Person {    private String name;    private Integer age;    public String getName() {        return name;    }    public void setName(String name) {        this.name = name;    }    public Integer getAge() {        return age;    }    public void setAge(Integer age) {        this.age = age;    }    @Override    public String toString() {        return "Person [name=" + name + ", age=" + age + "]";    }

PersonWrapper类

public class PersonWrapper {    private List<Person> persons;        public List<Person> getPersons() {        return persons;    }        public void setPersons(List<Person> persons) {        this.persons = persons;    }}

我的控制器方法

@RequestMapping(value="person", method=RequestMethod.POST,consumes="application/json",produces="application/json")    @ResponseBody    public List<String> savePerson(@RequestBody PersonWrapper wrapper) {        List<String> response = new ArrayList<String>();        for (Person person: wrapper.getPersons()){        personService.save(person);         response.add("Saved person: " + person.toString());    }        return response;    }

发送的请求是POST中的json

{"persons":[{"name":"shail1","age":"2"},{"name":"shail2","age":"3"}]}

回应是

["Saved person: Person [name=shail1, age=2]","Saved person: Person [name=shail2, age=3]"]
