属性不可读或具有无效的getter方法

Question

错误：org.springframework.beans.NotReadable财产异常： bean类[com.sprhib.model.团队]的无效属性“组织”： Bean属性“组织”不可读或具有无效的getter方法：getter的返回类型是否与塞特？

有表格：团队、组织。有一对多的关系。

团队模式

@Entity
@Table(name="teams")
public class Team {

    private Organization organization;

    @ManyToOne(fetch = FetchType.EAGER)
    @JoinColumn(name = "FK_Organization_id", nullable = false)
    public Organization getOrganization() {
        return organization;
    }

    public void setOrganization(Organization organization) {
        this.organization = organization;
    }
}

组织

@Entity
@Table(name = "organization")
public class Organization {
    private Set<Team> teams;

    @OneToMany(fetch = FetchType.EAGER, mappedBy = "organization")
    public Set<Team> getTeams() {
        return teams;
    }

    public void setTeams(Set<Team> teams) {
        this.teams = teams;
    }
}

JSP

<form:form method="POST" commandName="team" action="${pageContext.request.contextPath}/team/add.html">    
     <form:select path="organizations">
         <form:option value="${organization}">
             <c:out value="${organization.name}"/>
         </form:option>
     </form:select>
</form:form>

如何让spring让所有组织都使用JSP？

更新：

我使用controller将所有组织和新团队对象的列表传递给jsp：

@Controller
@RequestMapping(value="/team")
public class TeamController {

    @Autowired
    private TeamService teamService;

    @Autowired
    private OrganizationService organizationService;

    @RequestMapping(value="/add", method=RequestMethod.GET)
    public ModelAndView addTeamPage() {
        ModelAndView modelAndView = new ModelAndView("teams/add-team-form");
        modelAndView.addObject("team", new Team());
        modelAndView.addObject("organizations", organizationService.getOrganizations());

        return modelAndView;
    }

更新2：

commandName=“team”是否限制使用多个模型属性，在这种情况下有两个：组织和团队？如何让它工作？

自定义属性名称：commandName描述：表单对象在其下公开的模型属性的名称。默认为“command”。必需：false可以具有运行时值：true

Answer 1

<form:select path="organization">
    <form:options items="${organizations}" />
</form:select>

也可以同时使用这两个选项，例如用于添加默认的未选中选项：

<form:select path="organization">
    <form:option value="" label="- Select -"/>
    <form:options items="${organizations}" />
</form:select>

将被选择的值将在通过表单传递的团队bean中结束；路径属性用于确定将在团队中设置的属性，在这种情况下，它是组织（非组织）
