mybatis拦截器分页
以下是使用mybatis拦截器进行测试的步骤:
1.首先,在mybatis的配置文件中配置拦截器,例如:
```xml
<configuration>
<plugins>
<plugin interceptor="com.example.MyInterceptor">
<property name="someProperty" value="100"/>
</plugin>
</plugins>
</configuration>
```
2.然后,编写自己的拦截器类,例如:
```java
@Intercepts({
@Signature(type= Executor.class, method = "update", args = {MappedStatement.class, Object.class}),
@Signature(type= Executor.class, method = "query", args = {MappedStatement.class, Object.class, RowBounds.class, ResultHandler.class})
})
public class MyInterceptor implements Interceptor {
private Properties properties;
@Override
public Object intercept(Invocation invocation) throws Throwable {
// 拦截方法的执行
Object result = invocation.proceed(); // 对结果进行处理
return result;
}
@Override
public Object plugin(Object target) {
// 包装目标对象,返回代理对象
return Plugin.wrap(target, this);
}
@Override
public void setProperties(Properties properties) {
this.properties = properties;
}
}
```
3.最后,编写测试代码,例如:
```java
SqlSession sqlSession = sqlSessionFactory.openSession();
try {
BlogMapper mapper = sqlSession.getMapper(BlogMapper.class);
Blog blog = mapper.selectBlog(1);
} finally {
sqlSession.close();
}
```
以上就是使用mybatis拦截器进行测试的步骤。
