Question

我有一个Employee类，它将PersonalDetails类对象作为成员

public class Employee {

private long empId;

private PersonalDetails personalDetails = new PersonalDetails();
// getters setters

PersonalDetails类如下

/**

我使用spring form标签创建注册表单并添加如下代码

<label>
    <form:checkbox path="personalDetails.isPresentAddressSame" />
    Present address same as above
</label>

由于我有一个变量personalDetails并且它有一个字段isPresentAddressSame，它应该与getter setter匹配，但我收到了以下错误

There was an unexpected error (type=Internal Server Error, status=500).
Invalid property 'personalDetails.isPresentAddressSame' of bean class [com.hr.foundation.models.doc.models.employee.Employee]: Bean property 'personalDetails.isPresentAddressSame' is not readable or has an invalid getter method: Does the return type of the getter match the parameter type of the setter?

类型为String的其他字段与personalDetails.firstName之类的路径匹配，但不匹配此布尔字段

Answer 1

你没有包含PersonalDetails类的getter / setter，但Spring说这就是错误所在。

确保您拥有以下内容：

boolean isPresentAddressSame() { ... }

和

void setPresentAddressSame(boolean value) { ... }

你的错误可能是：

您在参数或返回类型中使用Boolean（请注意大写B）
您使用的getPresentAddressame仅允许Boolean（再次注明资本B），而不是isPresentAddressSame，boolean （小B）。

<强>澄清

变化：

public Boolean isPresentAddressSame() {
    return isPresentAddressSame;
}

public void setPresentAddressSame(Boolean isPresentAddressSame) {
    if (isPresentAddressSame) {
        presentAddress = permanentAddress;
    }
    this.isPresentAddressSame = isPresentAddressSame;
}

为：

public boolean isPresentAddressSame() {
    return isPresentAddressSame;
}

public void setPresentAddressSame(boolean isPresentAddressSame) {
    if (isPresentAddressSame) {
        presentAddress = permanentAddress;
    }
    this.isPresentAddressSame = isPresentAddressSame;
}

再次注意，此处的boolean使用较小的b。

Answer 2

尝试更改方法的签名：

public Boolean isPresentAddressSame() {
return isPresentAddressSame;

}

到

public Boolean getPresentAddressSame() {
return isPresentAddressSame;

}

如果您使用的是Spring，Spring会寻找 get 单词来解析bean的属性。

Spring Form嵌套对象布尔字段未得到解析
