如何正确设置休眠验证器 6.0.10.Final

Question

我试图设置注解验证器来验证对象而不使用验证器 class。起初我只包括库 validator-api 2.0.1.Final 一切似乎都工作正常但对象无法验证。

经过一番研究，我发现我需要添加：

<bean id="validator" class="org.springframework.validation.beanvalidation.LocalValidatorFactoryBean"/>

调度程序 servlet，但这是我非常头疼的时候。之后出现错误

然后，我在项目中添加了最新版本的hibernate validator，就出现了这个错误。

java.lang.NoClassDefFoundError: Could not initialize class org.hibernate.validator.internal.engine.ConfigurationImpl

尝试解决错误我尝试添加和删除不同的库和东西，并更改库的版本。我最终在我的项目中有了这些库，我没有使用 maven 来处理依赖关系，这让我更难找到错误。这是我项目中的库：

我用了几个小时来更改库，这是我认为可能有效但无效的最终结果。我是不是漏掉了什么重要的东西？

我的控制器：

@RequestMapping(value = "/add.html", method = RequestMethod.POST)
public ModelAndView addStaff(@Valid @ModelAttribute Staff staff,
        BindingResult result,
        HttpServletRequest request,
        HttpServletResponse response) throws Exception {

    if(result.hasErrors()){
        return new ModelAndView(parentFolder + "addStaff", "staff", staff);
    }

    return new ModelAndView( parentFolder + "addStaff", "staff", new Staff());

}

我的表格：

<div class="form-style">
<div class="form-group">
    <form:label path="id">Staff ID</form:label>
    <form:input path="id" type="text" class="form-control" placeholder="0123"/>
</div>
<div class="form-group">
    <form:label path="name">Name</form:label>
    <form:input path="name" type="text" class="form-control" placeholder="Adam Teh"/>
</div>
<div class="form-group">
    <form:label path="email">Email</form:label>
    <form:input path="email" type="email" class="form-control" placeholder="adam@example.com"/>
</div>
<div class="form-group">
    <form:label path="tel">Tel No</form:label>
    <form:input path="tel" type="tel" class="form-control" placeholder="0171234567"/>
</div>
<div class="form-group">
    <form:label path="role">Role</form:label>
    <form:select path="role" class="form-control">
        <form:option value="staff" label="staff" />
        <form:option value="admin" label="admin" />
    </form:select>
</div>
<div class="form-group">
    <label>Status</label>
    <div class="form-check">
        <form:radiobutton path="status" class="form-check-input" id="active" value="1" />
        <label class="form-check-label" for="active">active</label>
    </div>
    <div class="form-check">
        <form:radiobutton path="status" class="form-check-input" id="inactive" value="0"/>
        <label class="form-check-label" for="inactive">inactive</label>
    </div>
</div>

我的模式：

public class Staff {

@NotBlank(message = "Staff id cannot be empty.")
private String id;

@NotBlank(message = "Please type in your name")
private String name;

@Email(message = "There is problem with the email format.")
private String email;

@NotBlank(message = "Please key in your phone number")
@Pattern(message = "Please make sure your phone number only have 10 to 11 number only.", regexp = "^\d{10,11}$")
private String tel;


private Role role;

private Department department;

private boolean status;

public Staff(String id, String name, String email, String tel, Role role, Department department, boolean status) {
    this.id = id;
    this.name = name;
    this.email = email;
    this.tel = tel;
    this.role = role;
    this.department = department;
    this.status = status;
}

public Staff() {
}

public String getId() {
    return id;
}

public void setId(String id) {
    this.id = id;
}

public String getName() {
    return name;
}

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

public String getEmail() {
    return email;
}

public void setEmail(String email) {
    this.email = email;
}

public String getTel() {
    return tel;
}

public void setTel(String tel) {
    this.tel = tel;
}

public Role getRole() {
    return role;
}

public void setRole(Role role) {
    this.role = role;
}

public boolean getStatus() {
    return status;
}

public void setStatus(boolean status) {
    this.status = status;
}

public Department getDepartment() {
    return department;
}

public void setDepartment(Department department) {
    this.department = department;
}}

我认为这可能是 class 路径的问题，但向 class 路径添加额外的目录似乎根本不起作用。我不知道我在那里想念什么。

Answer 1

您可以尝试删除 javax.el-api-3.0.0.jar 吗？另一个 jar 已经包含 API 和实现，可能会导致冲突。

Answer 2

经过几个小时的搜索和尝试，我终于解决了我的问题。事实证明，我缺少一些导致 NoClassDefFoundError 错误的库。

这是我在项目中使用的库列表：

hibernate-validator-6.0.10.Final.jar
hibernate-validator-annotation-processor-6.0.10.Final.jar
hibernate-validator-cdi-6.0.10.Final.jar
验证-api-2.0.1.Final.jar
javax.el-3.0.1-b09.jar
同学-1.4.0.jar
jboss-logging-3.3.2.Final.jar

通过参考

解决这个问题后，又弹出一个错误，NoProviderFoundException。这是由代码行引起的

<bean id="validator" class="org.springframework.validation.beanvalidation.LocalValidatorFactoryBean"/>

我添加到我的调度程序 servlet。经过一些故障排除后，我找到了解决方案 https://hibernate.atlassian.net/browse/HV-1495 有人提到旧组 ID 问题。我试图检查我的图书馆组 ID，发现

org.hibernate

但新的群组 ID 是

org.hibernate.validator

因此，我将我的库更改为正确的组 ID，一切正常。并且我还删除了我添加到我的 dispatcher-servlet 中的代码行，因为问题仍然存在。即使我删除它，程序仍然能够运行.
