很明显形成不了对象是因为执行完最后一句的时候又去查了数据库

Answer 2

XML <action name="findAllRoles" class="roleAuthorityAssignAction" method="findAllRoles">

            <result type="json">

            </result> 

        </action>

Answer 3

我的源码是

private List<Roles> rolesList=new ArrayList<Roles>();//角色列表

    public List<Roles> getRolesList() {

        return rolesList;

    }

    public void setRolesList(List<Roles> rolesList) {

        this.rolesList = rolesList;

    }

    public String findAllRoles(){
        rolesList = roleManagerFacade.findAll();
        System.out.println("角色长度为："+rolesList.size());
        return SUCCESS;
    }

说句老实话，我是冲着标题来的···我以为是json难产了……

Answer 5

对象的每个属性，都要写上public的set和get方法？
