Question

当我尝试以这种方式构建表单时出现错误：

public class Person {

private String name;
private int age;

public Person() {
}

public Person(String name, int age) {
    this.name = name;
    this.age = age;
}

public int getAge() {
    return age;
}

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

public String getName() {
    return name;
}

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

}

@Controller
@RequestMapping("/")
public class TestController {

@GetMapping
public ModelAndView add() {
    ModelAndView mav = new ModelAndView("index");
    List<Person> persons = new ArrayList<>();
    persons.add(new Person("Neon", 4));
    mav.addObject("persons", persons);
    return mav;
}

}

<form class="form-horizontal">
        <div th:each="person,status : ${persons}" class="form-group" >
            <label>Name</label><input th:field="${persons[__${status.index}__].name}" th:value="${person.name}" />
            <label>Age</label><input th:field="${persons[__${status.index}__].age}" th:value="${person.age}" />
        </div>
        <button type="submit" class="btn btn-default">Submit</button>
    </form>

错误：

BindingResult和bean名称＆＃39;人员[0]＆＃39;可用作请求属性。

我想构建一个包含动态字段的表单

有人可以帮助我吗？

问题是，您不能使用pipeline { agent any stages { stage('build war') { agent { docker { image 'gradle:latest' reuseNode true } } steps { sh 'gradle war -b oven/build.gradle' } } stage('test') { steps { script { docker.image('mysql:latest').withRun('-e "MYSQL_ROOT_PASSWORD=password" -e "MYSQL_USER=root" -e "MYSQL_DATABASE=highlygroceries"') { c -> docker.image('munhunger/highly-oven').withRun('-e "test=test"') { h -> docker.image('mysql:latest').inside("--link ${c.id}:db") { sh 'while ! mysqladmin ping -hdb --silent; do sleep 1; done' } docker.image('munhunger/highly-oven').inside("--link ${c.id}:db -e 'DB_URL=db:3306' -e 'DB_PASS=password' -e 'DB_USER=root'") { sh 'sleep 5' } try { docker.image('gradle:latest').inside("--link ${h.id}:backend -e 'OVEN_URL=http://backend:8080'") { sh 'gradle test -b oven/build.gradle' } } catch (exc) { sh "docker logs ${h.id}" throw exc } } } } } } stage('build dockerimage') { steps { script { dir('oven') { def image = docker.build("munhunger/highly-oven") docker.withRegistry('https://registry.hub.docker.com', 'docker-hub-credentials') { image.push("${env.BUILD_NUMBER}") image.push("latest") } } } } } } }作为要发布的对象。如果你构建另一个java对象（在我的例子中，使用List的getter / setter）它应该可以工作

（示例）人员表格

List<Person> persons;

形式：

public class PersonForm {
    private List<Person> persons = new ArrayList<>();

    public List<Person> getPersons() {
        return persons;
    }

    public void setPersons(List<Person> persons) {
        this.persons = persons;
    }
}
