spring boot 项目访问controller报错 20C

搭建最基本的spring boot项目,版本是2.0.4.RELEASE。
整合mybatis, 从数据库中查询数据。
我想 通过浏览器,直接访问controller,看到json格式的数据;
但是,控制台中能看到查询的数据,接下来就报错。

Controller

 @Controller
public class UserController {
    @Autowired
    private UserService userService;

    @GetMapping("/findAll")
    @ResponseBody
    public List<User> findAll(){
        List<User> list = userService.findAll();

        System.out.println(Arrays.toString(list.toArray()));

        return userService.findAll();
    }

}

访问 http://localhost:1111/findAll
浏览器端没有显示json格式数据

控制台先显示查询出来的数据,然后报错;

 [User{id='122221', status='1', roleId='03bd3cc782b242bbab08c464ac35b0fa', 
 remark='监控大盘', UpdateTime=2018-08-16 15:10:27.0}, User{id='12222221', status='1', roleId='03bd3cc782b242bbab08c464ac35b0fa', remark='监控大盘', UpdateTime=2018-08-16 15:10:27.0}, User{id='yyx', status='1', roleId='yyx0101', remark='监控大盘', UpdateTime=2018-08-16 15:10:27.0}]

java.lang.ClassNotFoundException: com.fasterxml.jackson.module.jaxb.JaxbAnnotationIntrospector

按照之前的想法,加上了@ResponseBody 注解后,方法返回的数据应该被springboot内置的jackson,转换成了json格式的数据, 然后浏览器端直接显示的。
不知道问题出在哪里?

10个回答

试下去掉@ResponseBody,然后把@Controller换成@RestController

浏览器查看一下,数据是否返回页面了。
1.如果返回了,说明是页面数据接收错误。
2.如果页面没有返回,说明你后台的错误,找不到类,可以添加一下依赖

wuxiongbo
kepwo 回复weixin_42632514: 浏览器查看的响应的数据就是这个错误页面。应该是后台数据没有传输到浏览器来。依赖中重新配置了jacson ,以及添加了jaxb的依赖, 还是会出现一样的问题

@RestController 是将请求换成json格式输出,你应该是哪里的配置不对,可以看看我的这边文章:https://somta.com.cn/#/blog/view/ef507e4e6e28434d9787ec715d406491 ,我也是用spring boo 2.0 整合mybatis的,有详细的过程和代码

重点是java.lang.ClassNotFoundException: com.fasterxml.jackson.module.jaxb.JaxbAnnotationIntrospector,转json返回前台报错,pom.xml里面配置的架包不对,可以试试下面的添加配置

com.fasterxml.jackson.core
jackson-databind
2.4.0

    <groupId>com.fasterxml.jackson.core</groupId>
    <artifactId>jackson-core</artifactId>

kepwo 确实配置有问题,问题解决了一半,把eureka那段依赖注释掉后就正常访问了。。。但是接下来没办法用eureka了

kepwo 应该是转换这里有问题, 我添加这段依赖进去,springboot启动直接报错

楼主试一下@RequestMapping这个注解看看可以不。把@GetMapping换掉。

可能是你UpdateTime 这个时间格式 引起的
spring boot 默认支持一种时间格式 而你的时间格式不是默认格式导致报错
而你打印出来的时间格式 又不是java的格式 类似这种 'Wed Jul 06 10:17:48 CST 2016'
说明你格式化的啦 UpdateTime 这个属性是不是加啦 注解 格式化啦
如果你要格式化时间 不用再注解属性格式化 可以在配置文件直接加
spring.mvc.date-format=yyyy-MM-dd HH:mm:ss
spring.jackson.date-format=yyyy-MM-dd HH:mm:ss
spring.jackson.time-zone=GMT+8
ps: 加啦这个配置以后 前端提交的时候 也要这种时间格式提交数据不是会报错

确定了是方法返回数据后转换为json格式时出现问题;我在配置中改了一下,把eureka那段依赖注释掉后就正常访问了。。。问题解决了一半,但是接下来没办法用eureka了;

导入的spring boot项目,里面有的jsp页面可以访问,为什么我新建的jsp文件访问不了

application.properties ![图片说明](https://img-ask.csdn.net/upload/201909/23/1569206946_552631.png) controller ![图片说明](https://img-ask.csdn.net/upload/201909/23/1569206654_102464.png) 报错如下 ![图片说明](https://img-ask.csdn.net/upload/201909/23/1569206446_55413.png) 大致目录 ![图片说明](https://img-ask.csdn.net/upload/201909/23/1569209540_666232.png) 新手刚学的,希望有会的人,能够帮帮我,谢谢!

Spring boot的官方实例为何无法运行

本人小白,学Java没多久,刚刚开始接触Spring boot,环境都配置好了,上手用官网上QuickStart试了一下,结果跑不起来。 代码如下: ![图片说明](https://img-ask.csdn.net/upload/201511/19/1447913791_697663.jpg) pom代码: ``` <project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/xsd/maven-4.0.0.xsd"> <modelVersion>4.0.0</modelVersion> <groupId>com.sae.sg.lhf</groupId> <artifactId>hello</artifactId> <version>0.0.1-SNAPSHOT</version> <name>SampleController</name> <parent> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-parent</artifactId> <version>1.3.0.RELEASE</version> </parent> <dependencies> <dependency> <groupId>org.springframework.boot</groupId> <artifactId>spring-boot-starter-web</artifactId> </dependency> </dependencies> </project> ``` Java代码: ``` package hello; import org.springframework.boot.*; import org.springframework.boot.autoconfigure.*; import org.springframework.stereotype.*; import org.springframework.web.bind.annotation.*; @Controller @EnableAutoConfiguration public class SampleController { @RequestMapping("/") @ResponseBody String home() { return "Hello World!"; } public static void main(String[] args) throws Exception { SpringApplication.run(SampleController.class, args); } } ``` 几乎是完全按照官网上的实例照搬下来的,但是编译之后报错: ![图片说明](https://img-ask.csdn.net/upload/201511/19/1447914236_256736.jpg) 控制台最后输出也有ERROR: [ERROR] Failed to execute goal org.springframework.boot:spring-boot-maven-plugin:1.3.0.RELEASE:run (default-cli) on project hello: An exception occured while running. null: InvocationTargetException: Unable to start embedded Tomcat servlet container: Tomcat connector in failed state -> [Help 1] [ERROR] [ERROR] To see the full stack trace of the errors, re-run Maven with the -e switch.

[ERROR] [ERROR] For more information about the errors and possible solutions, please read the following articles: [ERROR] [Help 1] http://cwiki.apache.org/confluence/display/MAVEN/MojoExecutionException 求教是什么原因,应该如何修改代码?
