**问题**  
![这里写图片描述][70]

注意：本人使用的Spring Boot 2.0.2, 对1.5.x系列未必有用。官方文档在[这里][Link 1]

**直接解决办法**  
**0, 移除spring-boot-starter-security依赖**  
如果没有实际使用security的功能，可以直接移除spring-boot-starter-security依赖

**1， 使用默认用户和密码登录**  
默认用户名是user  
密码是程序启动时自动生成的一串字符串  
![这里写图片描述][70 1]

**2，禁用安全设置或者设置对应的用户和密码**  
可以在application.properteis中配置对应的用户和密码

也可以设置对应的用户名和密码  
spring.security.user.name=user1  
spring.security.user.password=password1

通过在启动main类上禁用

package com.yq;
    
    import org.slf4j.Logger;
    import org.slf4j.LoggerFactory;
    import org.springframework.beans.factory.annotation.Autowired;
    import org.springframework.boot.SpringApplication;
    import org.springframework.boot.autoconfigure.EnableAutoConfiguration;
    import org.springframework.boot.autoconfigure.SpringBootApplication;
    
    
    
    @SpringBootApplication(scanBasePackages = {
       "com.yq"})
    @EnableAutoConfiguration(exclude = {
    org.springframework.boot.autoconfigure.security.servlet.SecurityAutoConfiguration.class
    })
    public class WebSecurityDemoApp {
        private static final Logger log = LoggerFactory.getLogger(WebSecurityDemoApp.class);
    
        public static void main(String[] args) {
            SpringApplication.run(WebSecurityDemoApp.class, args);
        }
    
    }

**解析**  
我们的Spring Boot项目只要引用了如下依赖，默认就启动安全配置。

<dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-security</artifactId>
        </dependency>

如果既想使用security又不想每次输入用户名密码，可以直接在Application文件中禁用自动配置  
@EnableAutoConfiguration(exclude = \{  
org.springframework.boot.autoconfigure.security.servlet.SecurityAutoConfiguration.class  
\})

或者我们也可以配置指定的用户和密码，例如  
spring.security.user.name=user1  
spring.security.user.password=password1
