springboot-learning's Issues

使用Swagger时出现MethodArgumentTypeMismatchException

当调用url中包含参数的restful接口时，会报错，原因是指定为Long类型的参数在请求时被识别为String，导致类型不匹配报错。

以获取用户详细信息接口为例：
在SwaggerUI上输入value为1，然后try it out，结果是：

{
  "timestamp": 1488971240704,
  "status": 400,
  "error": "Bad Request",
  "exception": "org.springframework.web.method.annotation.MethodArgumentTypeMismatchException",
  "message": "Failed to convert value of type [java.lang.String] to required type [java.lang.Long]; nested exception is java.lang.NumberFormatException: For input string: \"{id}\"",
  "path": "/users/%7Bid%7D"
}

Chapter1

根pom.xml
依赖

org.springframework.boot
spring-boot-starter-web

以后可以不需要再依赖

org.springframework.boot
spring-boot-starter

redis连接根本就没用application.properties中的吖

 JedisConnectionFactory jedisConnectionFactory() {
        return new JedisConnectionFactory();
    }

public JedisConnectionFactory() {
        this.hostName = "localhost";
        this.port = 6379;
        this.timeout = 2000;
        this.usePool = true;
        this.poolConfig = new JedisPoolConfig();
        this.dbIndex = 0;
        this.convertPipelineAndTxResults = true;
}

这根本就是默认配置嘛~

chapter1-1编译报错

Project build error: 'packaging' with value 'jar' is invalid. Aggregator projects require 'pom' as packaging.

Spring Boot 2.x基础教程：使用EhCache缓存集群本地环境怎么部署?

本地环境只更改端口发现不生效

ehcache-1.xml

<cacheManagerPeerProviderFactory
            class="net.sf.ehcache.distribution.RMICacheManagerPeerProviderFactory"
            properties="hostName=localhost,
                        port=40001,
                        socketTimeoutMillis=2000,
                        peerDiscovery=manual,
                        rmiUrls=//localhost:40002/users" />

ehcache-2.xml

  <cacheManagerPeerProviderFactory
            class="net.sf.ehcache.distribution.RMICacheManagerPeerProviderFactory"
            properties="hostName=localhost,
                        port=40002,
                        socketTimeoutMillis=2000,
                        peerDiscovery=manual,
                        rmiUrls=//localhost:40001/users" />

chapter 2-1

idea测试出中文乱码问题。
java.lang.AssertionError: Response content
Expected: "[{"id":1,"name":"测试大师","age":20}]"
but: was "[{"id":1,"name":"???è???¤§???","age":20}]"
搜了半天，file encoding都改成utf-8了，但是还是乱码。

chapter3-3配置druid监控的问题

"第一步：在pom.xml中引入spring-boot-starter-actuator模块"关于这一步的问题

我使用的springboot版本是2.6.3，引入的swagger2启动报错：Failed to start bean ‘documentationPluginsBootstrapper’; nested exception is java.lang.NullPointerException，然后增加配置spring.mvc.pathmatch.matching-strategy=ant_path_matche解决上述启动报错的问题。

但是引入spring-boot-starter-actuator依赖，启动项目又出现上述问题。
好几天了，没找到怎么解决，(￣﹏￣；)

springboot 2.x 应用部署到weblogic12

hi，我是用springboot 1.5 能成功部署web到weblogic12上且不需要配置web.xml文件，只需配置weblogic.xml文件；但是使用springboot 2.1.9 怎么都不能成功部署，请问能出一节讲解如何部署springboot 2.x 应用至weblogic12年文章吗？谢谢🙏

Chapter3-12 JTA Test Failed

test2案例不通过，异常如下：

数据库也不回滚。
版本：spring boot 2.4.3

同时使用JPA与Swagger会报错

Rest api

Spring Boot中的缓存支持——EhCache使用有问题

你好，我看你给的示例Chapter-4-4-1中，当删除一条记录后，仍然可以通过findByName获取被删除的数据，这个应该是有问题的吧，自带的 delete方法执行时候应该是没有清楚缓存吧；

chapter1-1的博客和demo对不上

这个是你定义的格式controller的package但是demo里面不是还是在chapter11之下，这个在我本地测试中是错误的

多服务实例启动冲突

SpringBoot-Learning/2.x/chapter3-11/src/main/resources/application.properties

Line 6 in 2b01f8f

spring.flyway.locations=classpath:db/migration

按照Demo样例可以实现单服务使用 FlyWay 方式管理数据库脚本，但是在多服务下使用FlyWay异常。原因是因为 A服务启动后，数据库中已经存在 flyway_schema_history 表，而 B服务在启动的时候，直接报错。 org.flywaydb.core.api.exception.FlywayValidateException: Validate failed: Migrations have failed validation

日志这一章运行报错

如题

不同环境日志级别

你好，这个log4j的配置是不是有点问题啊，

elastic-job启动报错

SpringBoot-Learning/2.x/chapter7-2/启动报错，如下图。请求对zk版本有什么要求？

charpter1-1 Test junit4和5混用了

去掉 junit4相关的
@ RunWith(SpringRunner.class)

用junit5的
@ BeforeEach

chapter2-5 测试好像有问题

1.测试问题

@SpringBootTest(webEnvironment = SpringBootTest.WebEnvironment.DEFINED_PORT)改为@SpringBootTest好像就可以了。

代码读出来是有数据的，数据库工具里没数据，primary会回滚，secondary正常

Chapter3-1-1 请求如果是json是否会更好一点

Chapter3-1-1 中是Spring Boot构建RESTful API与单元测试，构造的请求是表单形式而返回的是json。如果请求是json是否会更好一点，可以增加请求为json的说明或者事例（采用RequestBody）。

chapter2-3 校验的错误不显示

发起校验不通过的请求时，确认校验是执行了的，但是没有错误的详细信息。swagger文档中所有的校验都没有体现。请问是什么原因。

chapter7-2 apache.shardingsphere.elasticjob 定时任务

出现：org.apache.zookeeper.KeeperException$OperationTimeoutException: KeeperErrorCode = OperationTimeout

2-2代码一样没有显示出来API

chapter3-10：使用单元测试执行成功也会回滚

单元测试会自动回滚添加@Rollback(false)

@Transactional
    @Rollback(false)
    @Test
    public void test(){
        userRepository.save(new User("AAA", 10));
        userRepository.save(new User("BBB", 20));
        userRepository.save(new User("CCC", 30));
    }

chapter3-1-3 读取freemarker 地址失败

你好，本人下载了Chapter3-1-3 这个代码后在本地运行spring-boot，启动spring-boot后访问http://localhost:8080/返回404页面。

SpringBootWithSwagger

Need help to read the tutorial from your website.

Hello @dyc87112 , I think this is a really good tutorial. I want to learn spring boot but your tutorial is in the Chinese language, I am converting all the pages into English using a google translate extension. it is ok. but when I click on Read the full button to read the full article it opens one qrcode dialog. then what to do I don't understand. when I scan it opens one URL on my mobile. and there is no login-related functionality on the website.
Could you please guide us on how to read the full article?

Chapter3-1-2 代码问题

Chapter3-1-2/src/main/java/com/didispace/web/HelloController.java

这里的ResponseBody是不是应该去掉?

    @ResponseBody
    @RequestMapping("/hello")
    public String hello() {
        return "Hello World";
    }

@Bean
public JdbcTemplate secondaryJdbcTemplate(@Qualifier("secondaryDataSource") DataSource secondaryDataSource) {
    return new JdbcTemplate(secondaryDataSource);
}

上面是配置文件里的代码，这样写不会覆盖吗，容器里毕竟只能有一个JdbcTemplate类型的对象
