Spring Boot

过滤器与拦截器

@ModelAttribute 和 HandlerInterceptor

@ModelAttribute，也属于控制器部分，只是在控制器之前执行，所以他们的顺序为：

InterceptorpreHandle
controller@ModelAttribute
controller@RequestMapping
InterceptorpostHandle
InterceptorafterCompletion

接口访问控制

@ModelAttribute

对控制器内所有接口生效（包括子类控制器），如需要对全部控制器生效，可以加上注解@ControllerAdvice

@ModelAttribute
public void resApiModel(HttpServletResponse response) throws java.lang.Exception {
    // 强制校验合法性
    if(verify() == null) {
        throw new Exception("访问合法性验证失败");
    };
}

HandlerInterceptor

spring.xml

<mvc:interceptors>
    <mvc:interceptor>
        <mvc:mapping path="/resApi/**"/>
        <bean class="com.chunshu.config.ResApiInterceptor"></bean>
    </mvc:interceptor>
</mvc:interceptors>

ResApiInterceptor

package com.chunshu.config;

import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;

import org.springframework.stereotype.Component;
import org.springframework.web.servlet.HandlerInterceptor;
import org.springframework.web.servlet.ModelAndView;

import com.alibaba.fastjson.JSON;
import com.chunshu.common.result.JsonResult;

@Component
public class ResApiInterceptor implements HandlerInterceptor {

    @Override
    public boolean preHandle(HttpServletRequest httpServletRequest, HttpServletResponse response, Object o) throws Exception {
        if(verify() == false) {
            JsonResult obj = renderError("访问合法性验证失败");
            response.setCharacterEncoding("UTF-8");
            response.setContentType("application/json; charset=utf-8");
            response.getWriter().write(JSON.toJSONString(obj));
            return false;
        }
        return true;
    }

    @Override
    public void postHandle(HttpServletRequest httpServletRequest, HttpServletResponse httpServletResponse, Object o, ModelAndView modelAndView) {
        httpServletResponse.setCharacterEncoding("UTF-8");
        httpServletResponse.setContentType("application/json; charset=utf-8");
    }

    @Override
    public void afterCompletion(HttpServletRequest httpServletRequest, HttpServletResponse httpServletResponse, Object o, Exception e) {
        httpServletResponse.setCharacterEncoding("UTF-8");
        httpServletResponse.setContentType("application/json; charset=utf-8");
    }
}

@PostConstruct 执行顺序

在类B中的@PostConstruct进行初始化依赖于A类的@PostConstruct初始化。

Tip

@PostConstruct和@Autowired、构造函数的执行顺序

构造方法 > @Autowired > @PostConstruct

多个类中使用@PostConstruct，加载先后顺序_janet1100的博客-CSDN博客_多个postconstruct顺序

实测`@Order(Ordered.HIGHEST_PRECEDENCE)`无效

在spring中，初始化的操作是在管理初始化的BeanPostProcessor中进行的，BPP依次反射调用初始化方法。而执行的顺序却是由beanDefinitionNames这个List控制的，但问题是beanDefinitionNames 并没有根据@Order做排序，也就是不管是MyBean1,MyBean2,其实都是根据扫描BeanDefinition放入beanDefinitionNames列表的顺序初始化的。正因为MyBean2的位置在配置文件中定义的更靠前，所以它被先扫描加入beanDefinitionNames列表了！

总的来说，用户业务bean初始化方法的调用顺序是在扫描bean definition后就确定了的。

你用@Order控制过Spring的@PostConstruct调用顺序吗？可能写错了 - 知乎 (zhihu.com)

`@DependsOn`不能用于控制`@PostConstruct`的执行顺序

@DependsOn合约仅保证已构造bean并已设置属性。这并不能保证调用任何@PostConstruct方法。

让它工作的方法是让“dependee”类（其他人依赖的类）实现“InitializingBean”类，这需要实现“afterPropertiesSet（）”方法。我将我的“init（）”方法的原始主体放入此方法中。我确认现在在依赖于此的任何类之前执行此操作。

java - 为什么Spring会忽略我的@DependsOn注释？ - Thinbug

@DependsOn可以控制bean的创建、初始化（InitializingBean）、销毁方法执行顺序。

示例：假如有三个Bean类叫Aaa、Bbb、Ccc分别实现了如下两个接口。 org.springframework.beans.factory.InitializingBean org.springframework.beans.factory.DisposableBean

Ccc通过@DependsOn指定依赖bean创建的顺序为Bbb > Aaa
@DependsOn({"bbb","ccc"})
@Service
public class Aaa implements InitializingBean, DisposableBean {
       private static final Logger logger = LoggerFactory.getLogger(Aaa.class);

       public Aaa() {
           logger.info(this.getClass().getName() + " Construction");
       }

       @Override
       public void afterPropertiesSet() throws Exception {
           logger.info(this.getClass().getName() + " afterPropertiesSet");
       }

       @Override
       public void destroy() throws Exception {
           logger.info(this.getClass().getName() + " destroy");
       }
}
Spring中@DependsOn注解的作用及实现原理解析_java_脚本之家 (jb51.net)

可以利用spring的依赖关系来处理`@PostConstruct`执行顺序的问题

@Component
public abstract class B {

	/*
	 * 此处注入A以保证A在B之前执行
	 */
	@Autowired
	A a;

	@PostConstruct
	private void init() {
    
    }
}

多个类中使用@PostConstruct，加载先后顺序有时候Class A 中@PostConstruct 注解的方法中的代码执行，需要等待Class B 中@PostConstruct 注解方法中的代码执行完后，拿到结果，才能执行，也就是中A中某些代码的执行需要依赖B中代码执后的结果。此时就需要B先执行完，再执行A，

可以在A中先注入B。

@RequestMapping 的继承问题

子类的@RequestMapping注解会覆盖父类的@RequestMapping注解，子类配置了@RequestMapping之后，父类的@RequestMapping（地址、produces等）将失效
子类不配置@RequestMapping注解，父类地址将会被继承：父类地址 + 子类方法地址

如果接口有统一的前缀，可以把前缀配置在父类：

@CrossOrigin(origins = "*", maxAge = 3600)
@RestController
@RequestMapping(value="/resApi", produces="application/json;charset=UTF-8")
public class BaseApiController extends BaseController {
    
}

子类：

@RestController
public class ADS_BController extends BaseApiController {
    
    @RequestMapping("/getXXXX")
    @ResponseBody
    public Object getFlightNo(@RequestParam Date beginTime,@RequestParam Date endTime) {
        return xxx
    }
}

接口地址：/resApi/getXXXX

若子类需要配置另外的前缀，那么就需要在子类重新配置@RequestMapping。

Maven打包时引入本地jar包_maven将本地jar包打入一个包里供其他项目引用-CSDN博客

I have a similar issue today, and stuck me half day to fix it.

For most case, using below is fine for developing.

引入本地 jar 包：
<dependency>
 <groupId>com.netease</groupId>
 <artifactId>thrift</artifactId>
 <version>1.0</version>
 <scope>system</scope>
 <systemPath>${project.basedir}/lib/prome-thrift-client-1.0.0.jar</systemPath>
</dependency>
If you put the jar to a correct path, then it's fine to run in both IDEA and Eclipse.

After you deploy the jar to a server or run the jar locally, then it may throws ClassNotFoundException.

If you are using spring-boot, you still need below plugin:

使用 IDE 运行正常，但部署到服务器或本地运行 jar 包报ClassNotFoundException，如果使用 spring boot，还需要以下插件：
<plugin>
 <groupId>org.springframework.boot</groupId>
 <artifactId>spring-boot-maven-plugin</artifactId>
 <configuration>
         <includeSystemScope>true</includeSystemScope>
 </configuration>
</plugin>
After run mvn clean package, then you can find the jar under /BOOT_INF/lib.

Between, if your package is war, then you still need this plugin:

如果是 war 包，还需要以下插件：
<plugin>
     <groupId>org.apache.maven.plugins</groupId>
     <artifactId>maven-war-plugin</artifactId>
     <configuration>
         <webResources>
             <resource>
                     <directory>lib</directory>
                     <targetPath>BOOT-INF/lib/</targetPath>
                     
                     <includes>
                         <include>**/*.jar</include>
                     </includes>
             </resource>
         </webResources>
     </configuration>
</plugin>
-----------------Another Way--------------------

You can using this plugin to replace maven-war-plugin:

可以使用这个插件代替maven-war-plugin：
<plugin>  
   <artifactId>maven-compiler-plugin</artifactId>  
    <configuration>  
         <source>1.8</source>  
         <target>1.8</target>  
         <compilerArguments>  
             <extdirs>${project.basedir}/lib</extdirs>  
         </compilerArguments>  
   </configuration>  
</plugin>  
And add the resource:

添加资源：
<resources>  
 <resource>  
     <directory>lib</directory>  
     <targetPath>BOOT-INF/lib/</targetPath>  
     <includes>  
         <include>**/*.jar</include>  
     </includes>  
 </resource>
 <resource>
     <directory>src/main/resources</directory>
     <targetPath>BOOT-INF/classes/</targetPath>
 </resource> 
</resources>
