SpringMVC使用校验validator校验对象属性

1.pom.xm添加依赖

<dependency>
            <groupId>javax.validation</groupId>
            <artifactId>validation-api</artifactId>
        </dependency>
        <dependency>
            <groupId>org.hibernate</groupId>
            <artifactId>hibernate-validator</artifactId>
        </dependency>
<dependency>
            <groupId>com.fasterxml.jackson.core</groupId>
            <artifactId>jackson-core</artifactId>
            <version>2.8.7</version>
        </dependency>
        <dependency>
            <groupId>com.fasterxml.jackson.core</groupId>
            <artifactId>jackson-annotations</artifactId>
            <version>2.8.7</version>
        </dependency>
<dependency>
            <groupId>com.fasterxml.jackson.core</groupId>
            <artifactId>jackson-databind</artifactId>
            <version>2.8.7</version>
        </dependency>

 

2.配置文件.xml

<!-- 校验参数 -->
    <bean >
        <property name="basenames">
            <list>
                <value>classpath:message/message</value>
                <value>classpath:org/hibernate/validator/ValidationMessages</value>
            </list>
        </property>
        <!--默认为false，这样当Spring在ResourceBundle中找不到messageKey的话，就抛出NoSuchMessageException，   把它设置为True，则找不到不会抛出异常，而是使用messageKey作为返回值。-->
        <property name="useCodeAsDefaultMessage" value="false"/>
        <property name="defaultEncoding" value="UTF-8"/>
        <property name="cacheSeconds" value="600"/>
    </bean>

    <bean >
        <property name="providerClass" value="org.hibernate.validator.HibernateValidator"/>
        <property name="validationMessageSource" ref="commonProvider.messageSource"/>
    </bean>

    <bean />
    <!-- 参数校验 -->
    <bean >
        <property name="messageSource" ref="commonProvider.messageSource" />
        <property name="validator" ref="commonProvider.validator" />
    </bean>

3.对象.java

public class test {
    @NotNull(message = "测试id不能为空", groups = { First.class })
    private String id;
    @NotNull(message = "测试name不能为空", groups = { Second.class })
    private  String name;

    public String getId() {
        return id;
    }

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

    public String getName() {
        return name;
    }

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

    public test(String id, String name) {
        this.id = id;
        this.name = name;
    }
    public interface First {

    }
    public interface Second {

    }

4.调用

1).

public <T> T checkObjParamValidate(@NotNull T t, Class<?>... groups) {

2).

.checkObjParamValidate(test,com.jd.bjshare.domain.test.First.class,com.jd.bjshare.domain.test.Second.class);

3).

validator.validate(t, groups);

5.页面返回结果

{"code":1,"msg":"测试id不能为空,测试name不能为空","data":{}}
