Spring Boot中使用MongoDB

Sun, 14 Apr 2019 00:00:00 +0000

pom文件中

<dependencies>
        <dependency>
            <groupId>org.springframework.boot</groupId>
            <artifactId>spring-boot-starter-data-mongodb</artifactId>
        </dependency>
</dependencies>

application.properties中

##mongo配置
spring.data.mongodb.host=127.0.0.1
spring.data.mongodb.port=27017
spring.data.mongodb.database=test

主类中

@SpringBootApplication(exclude = DataSourceAutoConfiguration.class)

spring boot和React跨域请求解决

首先是在React，前端上只需要注意请求是POST请求，因为GET请求会有一个错误，然后就是用fetch传输了

    handleSubmit = (e) => {
        e.preventDefault();
        this.props.form.validateFields((err, values) => {
            if (!err) {
                console.log('Received values of form: ', values);
                let data = new FormData();
                data.append("userName",values.userName);
                data.append("password",values.password);
                data.append("remember",values.remember);
                fetch("http://localhost:8080/post",{
                    method: 'POST',
                    body : data
                }).catch();
            }
        });
    };

然后主要是在spring boot这里，后端控制器要写入一行
