Question

一直试图从不同的程序中获取价值，但没有成功。

控制器：

def list(){
    Student stud = new Student()
    def listStudents = stud.executeQuery("from Student")
    listStudents.each{ lisStud->

    println "email = ${lisStud.email}"
    render view:"/layouts/listOFstudents"
}

表格

<table>
<tr>
    <g:each in="${lisStud}">
    <td>${lisStud.email}</td>


    </g:each>

Answer 1

class HelloController {
def index() {
    def list = []
    list << new Person(firstName: 'John', lastName:'Doe', age:50)
    list << new Person(firstName: 'Jane', lastName:'Smith', age:45)
    list << new Person(firstName: 'Sam', lastName:'Robinson', age:47)
    [ list:list ]
}

}

只是不要将页面渲染到任何其他页面然后索引

Answer 2

控制器：

def list(){
 Student stud = new Student()
 def listStudents = stud.executeQuery("from Student")
 def displayStudentList = []
 listStudents.each{ lisStud->
  println "email = ${lisStud.email}"
  displayStudentList += it 
 }
 [displayStudentList : displayStudentList]
}

查看：

的list.gsp

<g:each in="${displayStudentList}" var="lisStud">
  <td>${lisStud.email}</td>
</g:each>

如何从控制器获取列表的值到gsp
