如何构建SpringBoot MongoDb RestfulApi? - groko

打开pom.xml文件,添加Spring Data Rest和Spring Data Mongo依赖项:

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

模型类:

<b>public</b> <b>class</b> Customer implements Serializable {
 
    <b>private</b> <b>static</b> <b>final</b> <b>long</b> serialVersionUID = 1L;
 
    @Id
    <b>private</b> Long id;
 
    <b>private</b> String firstName;
 
    <b>private</b> String lastName;
 
    <b>private</b> <b>static</b> AtomicLong COUNTER = <b>new</b> AtomicLong(0L);
    
    @PersistenceConstructor
    <b>public</b> Customer() {
        <b>this</b>.id = COUNTER.incrementAndGet();
    }
 
    @Override
    <b>public</b> String toString() {
        <b>return</b> String.format(<font>"Customer[id=%d, firstName='%s', lastName='%s']"</font><font>, id, firstName, lastName);
    }
 
 
    <b>public</b> String getFirstName() {
        <b>return</b> firstName;
    }
 
 
    <b>public</b> <b>void</b> setFirstName(String firstName) {
        <b>this</b>.firstName = firstName;
    }
 
 
    <b>public</b> String getLastName() {
        <b>return</b> lastName;
    }
 
 
    <b>public</b> <b>void</b> setLastName(String lastName) {
        <b>this</b>.lastName = lastName;
    }
}
</font>

通过扩展接口MongoRepository创建MongoDb存储库:

@RepositoryRestResource(collectionResourceRel = <font>"customer"</font><font>, path = </font><font>"customer"</font><font>)
<b>public</b> <b>interface</b> CustomerRepository <b>extends</b> MongoRepository<Customer, String> {
    List<Customer> findByLastName(@Param(</font><font>"name"</font><font>) String name);
}
</font>

在上面的代码中,我们定义了一个自定义方法,用于按姓氏查找列表客户。

打开application.properties来配置MongoDB:

spring.data.mongodb.database=restapi
spring.data.mongodb.port=27017

运行MongoDB服务器。然后运行Spring Boot项目。

GET请求:localhost:8080
