Hibernate-validator AOP

Verification of background methods can be implemented in spring interceptor

The configuration file is as follows:

<AOP: aspectj-autoproxy proxy-target-class = "true"/> <! -- Exception notification class --> <bean id = "exceptionadvice" class = "com. Exception. Advice. exceptionadvice"/> <! -- Exception mark cut point --> <bean id = "exceptionpointcut" class = "com. exception. advice. predictionpointcut "> <property name =" regexpmethodpointcut "> <ref bean =" regexpmethodpointcut "/> </property> </bean> <! -- The actual vertex of the exception --> <bean id = "regexpmethodpointcut" class = "org. springframework. AOP. support. jdkregexpmethodpointcut "> <property name =" patterns "> <list> <value> COM. example. *.. * </value> </List> </property> </bean> <! -- Exception section --> <bean id = "exceptionpointcutadvisor" class = "org. springframework. AOP. support. defaultpointcutadvisor "> <property name =" pointcut "> <ref bean =" exceptionpointcut "/> </property> <property name =" advice "> <ref bean =" exceptionadvice "/> </property> </bean>

 

The section is as follows:

 

Public class exceptionadvice implements throwsadvice, methodbeforeadvice, rule {@ override public void before (method, object [] ARGs, object target) throws throwable {methodvalidator validator = validation. byprovider (hibernatevalidator. class ). configure (). buildvalidatorfactory (). getvalidator (). unwrap (methodvalidator. class); set <methodconstraintviolation <Object> violations = Validator. validateallparameters (target, method, argS, new class [] {}); If (! Violations. isempty () {new exception ("", "parameter verification exception ");}}.....

Cut point:

public class ExceptionPointcut extends StaticMethodMatcherPointcut{    private JdkRegexpMethodPointcut regexpMethodPointcut;        /**     * {@inheritDoc}     */    @Override    public boolean matches(Method method, Class<?> targetClass)    {        return regexpMethodPointcut.matches(method, targetClass);    }        public JdkRegexpMethodPointcut getRegexpMethodPointcut()    {        return regexpMethodPointcut;    }    public void setRegexpMethodPointcut(JdkRegexpMethodPointcut regexpMethodPointcut)    {        this.regexpMethodPointcut = regexpMethodPointcut;    }    }

 

Interface Definition

public interface CarManager{    public void add(@Valid @NotNull Car car);        @NotNull    public String dele(@NotNull @UTFSize(min = 2, max = 8) String name);        public int age(@Min(10) @Max(12) int age);}
